Test: Location and Movement, Translations - Year 5 MCQ

Translating a shape 5 units to the right and 2 units up results in the shape maintaining its size and orientation while simply changing its position on the coordinate grid. This process exemplifies how translations work, demonstrating that the shape's properties remain unchanged despite its new location.

The point (0, 0) represents the origin in the coordinate system, where both the x and y values are zero. This point serves as the reference point from which all other points are measured, making it essential for plotting and understanding coordinates.

The coordinates provided form a linear pattern where the relationship can be expressed as y = 2x + 2. This indicates that for every increase of 1 in x, y increases by 2, demonstrating a consistent linear relationship that can be graphed as a straight line.

To find the new coordinates after translation, add the translation vector (-2, 3) to the original coordinates (4, 7). This results in (4 - 2, 7 + 3) = (2, 10). This illustrates how translations can be calculated step by step to determine new positions of points.

The translation vector can be determined by subtracting the original coordinates from the new coordinates. Thus, (8, 6) - (3, 4) results in the vector (5, 2). This means that the point moved 5 units to the right and 2 units up, which is the essence of a translation.

The lines that connect the corresponding vertices of the original and translated shapes are always parallel to each other and of equal length. This property emphasizes the fact that the translation preserves the shape's dimensions and proportional relationships, ensuring that the original shape and its translation are congruent.

To find the fourth vertex of a rectangle, you can identify the missing coordinate by ensuring that opposite sides are equal and parallel. Given the vertices (1, 2), (3, 2), and (3, 4), the fourth vertex must be (1, 4), completing the rectangle and maintaining the property of right angles at each corner.

When a shape undergoes a translation, each vertex moves the same distance and in the same direction. This property ensures that the overall structure and relationships between the vertices remain consistent, allowing for the original shape to be perfectly recreated at its new location.

Translations are specified by indicating how far a shape moves horizontally (left or right) and vertically (up or down). This means that to describe a translation, one must provide two numerical values that represent these movements, making it easy to visualize the new position of the shape on a coordinate plane.

Translations preserve the dimensions and properties of a shape, meaning that the size, shape, and orientation remain unchanged throughout the transformation. This characteristic is fundamental to understanding how translations operate in geometry.

Translations do not alter the distances between points in a shape. The distances remain unchanged because each point moves the same distance in the same direction, preserving the relationships and proportions of the original shape throughout the translation process.

The statement refers to a reflection, which is a transformation that creates a mirror image of a shape over a specified line, in this case, the x-axis. Unlike translations, reflections change the orientation of the shape, which is a key distinguishing feature of this type of transformation.

A coordinate is expressed as an ordered pair in the format (x, y), where x represents the horizontal position and y represents the vertical position. For instance, the coordinate (2, 5) indicates that the point is located 2 units to the right and 5 units up from the origin (0, 0) on a coordinate grid.

Translations are fundamental in geometry because they maintain the size, shape, and orientation of figures while allowing them to be moved to different locations. This property is crucial for understanding congruence and similarity among shapes and forms the basis for many geometric transformations.

To find the fourth vertex of a rectangle when three vertices are known, you can determine the missing vertex by using the coordinates of the other three. The properties of rectangles—specifically, that opposite sides are equal and parallel—allow for straightforward calculations to deduce the missing vertex's coordinates.

The reverse operation for a translation involves subtracting the same values that were added during the original translation. For example, if shape A was translated to shape B by moving 5 units right and 2 units up, moving back to shape A requires subtracting 5 from the x-coordinate and 2 from the y-coordinate of shape B.

To find the new coordinate of a vertex after translation, simply add the translation vector to the original coordinates. For the vertex at (2, 2), applying the vector (3, -1) results in (2 + 3, 2 - 1) = (5, 1). This calculation shows how translations systematically change vertex positions.

A key characteristic of a rectangle's vertex coordinates is that they must create right angles at each corner. This property is essential in defining a rectangle, as all angles in a rectangle are right angles, which distinguishes it from other quadrilaterals.

A translation refers to moving a shape along a straight path without altering its dimensions or orientation. This means that every point of the shape shifts the same distance in the same direction. For example, if a triangle is translated 3 units to the right and 2 units up, each vertex of the triangle will move precisely those amounts, preserving the triangle's overall shape and size.

Rotating a square 90 degrees does not qualify as a translation because it changes the orientation of the shape. Translations strictly involve sliding the shape in a straight line without altering its size, shape, or orientation, while rotations involve turning the shape around a point.
