rigid motions

100

A triangle is reflected over x-axis. If one vertex was at (3,5) , what are the new coordinates after the reflection?

3,-5

200

A square is rotated 90 degress clockwise around the origin. What happens to the point (4,-2) ?

-2,-4

300

Describe whether a translation changes the size or shape of figure and explain why.

A translation does not change the size or shape of a figure it moves the distance between the points

400

A rectangle is translated 6 units right and 3 units down. What are the new coordinates of the point (1,7) ?

7,4

500

determine if a reflection and a rotation are examples of rigid motions. Explain your answer!

Yes, reflections and rotations are rigid motions because they change distance and a angle measure.

dilations and transformation

100

A point (2,4) is dilated by a scale factor of 2 centered at the origin. What are the new coordinates?

4,8

200

Explain the difference between a dilation and a rigid motion

A dilation changes the size of a figure, while a rigid motion perserve the size and shape of a figure.

300

A triangle is enlarged with a scale factor of 1/2. Does the image get bigger or smaller?

smaller

400

Describe what happens to the coordinates of a figure after a reflection over the y- axis.

The x-coordinate of each point changes its going, while the y-coordinate remains the same.

500

A figure is translated 4 units left and then reflected over the x-axis. Describe the combined transformation.

The figure is translated 4 units to the left and then reflected across the x-axis
