IM 8.1.8 Lesson: Rotation Patterns
Here is a right isosceles triangle. Rotate triangle ABC 90 degrees clockwise around B.
Here is a right isosceles triangle. Rotate triangle ABC 180 degrees clockwise around B.
Here is a right isosceles triangle. Rotate triangle ABC 270 degrees clockwise around B.
What would it look like when you rotate the four triangles 90 degrees clockwise around ? 180 degrees? 270 degrees clockwise?
Create a segment AB and a point C that is not on segment AB.
Rotate segment around point .
Rotate segment around point .
Construct the midpoint of segment AB with the Midpoint tool.
Rotate segment around its midpoint. What is the image of ?
What happens when you rotate a segment ?
Here are two line segments.
Is it possible to rotate one line segment to the other? If so, find the center of such a rotation. If not, explain why not.
Here is a diagram built with three different rigid transformations of triangle ABC.
Describe a rigid transformation that takes triangle to triangle .
Describe a rigid transformation that takes triangle to triangle .
Describe a rigid transformation that takes triangle to triangle .
Do segments , , , and all have the same length? Explain your reasoning.
