Angle Measures of Rotated Figures

Explore how figures are affected by rotations and verify that their angle measures remain unchanged.

Tarea 1

Tarea 2

How are the image and the pre-image different?

Tarea 3

What stays the same after a rotation?

Tarea 4

How can you use the triangles in the grid to show that an image has the same angle measurements as a pre-image?

Tarea 5

Can you use the triangles in the grid in the same way to show that the angle measurements of the image and pre-image of a right triangle are the same? Why or why not?
