and another is DIE, DFI, DOA, DQA, and GHI is the 5 triangle

and DCA, DBA is the 2 triangle and DEF and ABC so that according to the figure the total no. of triangle is
8 + 10 + 5 + 2 + 1 + 1
= 27

The given series : 5, 8, 11, 14, …
a = 5
d = 8 – 5 = 3
a(n) = a + (n – 1) x d
10th term = a(10) = a + (10 – 1) x d
= 5 + 9 x (3)
= 5 + 27
= 32

AP: 10, 6, 2, …
a = 10, d = - 4
Sum of first n terms = S(n) = (n/2) x [2a + (n – 1) x d]
S5 = (5/2) x [2 x (10) + (5 – 1) x (-4)]
= (5/2) x [20 + 4 x (-4)]
= (5/2) x (20 – 16)
= (5/2) x (4)

HTTPS:
HTTPS stands for Hypertext Transfer Protocol Secure. It is the secure version of HTTP, which is the protocol used for transmitting data over the internet.
What does the 'S' in HTTPS stand for?
The 'S' in HTTPS stands for:
- Secured: The 'S' in HTTPS stands for 'Secured'. It indicates that the communication between the web browser and the web server is encrypted and secure.
How does HTTPS work?
HTTPS works by using SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocols to encrypt the data transmitted between the web browser and the web server. Here is a brief overview of how HTTPS works:
1. Handshake: The web browser sends a request to the web server to establish a secure connection.
2. Server authentication: The web server sends its SSL/TLS certificate to the web browser to prove its identity.
3. Encryption: The web browser and the web server negotiate an encryption algorithm and exchange encryption keys.
4. Data transmission: The web browser and the web server encrypt and decrypt the data using the shared encryption keys, ensuring that the data cannot be intercepted or tampered with during transmission.
Why is HTTPS important?
HTTPS is important for several reasons:
- Data security: HTTPS ensures that the data transmitted between the web browser and the web server is encrypted and secure, protecting it from unauthorized access.
- Authentication: HTTPS verifies the identity of the web server, ensuring that the user is connecting to the intended website and not a malicious imposter.
- Trust and credibility: Websites that use HTTPS are often seen as more trustworthy and credible by users, as they prioritize data security.
Conclusion:
In summary, the 'S' in HTTPS stands for 'Secured'. HTTPS is crucial for ensuring the security and integrity of data transmitted over the internet, providing encryption, authentication, and trustworthiness.

Representation of Digital Signals:

• Binary Codes: Digital signals can be represented using binary codes, which are sequences of 0s and 1s.


• 0 and 1: Another common representation of digital signals is using the binary digits 0 and 1.


• High and Low: Digital signals can also be represented using the concepts of "high" and "low" voltage levels. A high voltage level represents a logical 1, while a low voltage level represents a logical 0.


• All of the Above: The correct answer is option D, as digital signals can be represented using binary codes, 0 and 1, as well as high and low voltage levels.

By utilizing these various representations, digital signals can be transmitted, stored, and processed in digital systems. The choice of representation depends on the specific application and the requirements of the system.

Co-teaching involves two teachers working together to plan a classroom and make assessments on one group of students. A strategy to pair teaching candidates with more experienced teachers as a mentor.

Models of Co-teaching

• One Teach, One Observe: One teacher is directly teaching or giving instruction to students while the other teacher acts as observes to students for evidence of learning.
• One Teach, One Assist. One teacher would kee responsible for teaching the students while the other teacher circulated through the room providing not attracting attention assistance to students as per students' needs.
• Parallel Teaching: The class is divided into two groups and each teacher teaches the same information at the same time with a different method or thinking according to teacher and children respectively.
• Station Teaching. Teachers divide content /chapters and students. Each teacher then teaches the content/chapter to one group and repeats the instruction for the other group.
• Alternative Teaching:  In alternative teaching, one teacher takes responsibility for the large group of students while the other works with a smaller group of students. This teaching arises in which several students need specialized attention.
• Team Teaching: Both the teachers are delivering the same instruction at the same time to the class. Some teachers refer to this type of teaching as having one brain in two bodies. Others call it tag-team teaching.

Since parallel teaching involves teaching the same information at the same time with a different method or thinking, thereby it reinforces the knowledge as well provides a better road map for an inclusive teaching/classroom.

Additional Information

Computer-mediated teaching: Computer-mediated teaching refers to students' communication via computers with the help of their teacher and it includes many different forms of synchronous, asynchronous, or real-time interaction that students have with each other using computers as tools to exchange text, images, audio, and video.

Blended learning: In blended learning teacher combines online educational materials and gives opportunities for online interaction with traditional place-based classroom methods. It is also known as hybrid learning.

Role Play: In role-play, students apply their thinking as they are put in the role of a decision-maker who must make a decision regarding a policy, resource, or some other outcome. This allows students to interact with their classmates as they try to complete the task assigned to them in their specific role students are more engaged. This technique is an excellent tool for engaging students.

Vygotsky's theory of cognitive development focuses on linguistic, social and cultural development in his theories but does not focus on biological development. It is because of social interactions or imaginative plays, cognitive development takes place in the children. He believes that socialization starts with the schools and communities that engage children in discovering and exploring new things. Hence, the correct answer is, 'Biological.'

Inclusive Education: It is concerned with the learning and participation of all students vulnerable to exclusionary pressures not only those with impairments or those who are categorized ‘having special educational needs'. Inclusion is all about embracing all.

Jean Piaget has proposed four stages in his cognitive development theory. The First stage is the sensorimotor stage which occurs from birth to 2 years, second is the pre-operational stage which occurs from 2 to 7 years of age, the third is the concrete operational stage which occurs from 7 to 11 years of age. This is the stage when a child begins to think logically about objects and events. Last is the formal operational stage which occurs above 12 years of age.
Hence, the correct answer is, 'Concrete operational stage.'
