IM Geo.6.1 Lesson: Rigid Transformations in the Plane
How far is point A from point B?
What transformations will take point A to point B?
Rotate Figure H clockwise using center (2,0) by 90 degrees. Translate the image by the directed line segment from (2,0) to (3,-4). Label the result R.
Rotate Figure H across the y-axis. Rotate the image counterclockwise using center (0,0) by 90 degrees. Label the result L.
Calculate the length of each side in triangles and .
Calculate the measure of each angle in triangles and .
Because the triangles are congruent, there must be a sequence of rigid motions that takes one to the other. Find a sequence of rigid motions that takes triangle to triangle .
The triangles are congruent. How do you know this is true?
What single transformation would take triangle to triangle ?
