Question

4.1: Angle Articulation

Triangle A'B'C' is a dilation of triangle ABC using center P and scale factor 2.

1. What do you think is true about the angles in A' B'C' compared to the angles in ABC?

2. Use the tools available to figure out if what you thought was true is definitely true for
these triangles.

3. Do you think it would be true for angles in any dilation?

Answer 1

1.) The measure of each angle of ABC is equal to the corresponding angle of A'B'C' , the measures of this angle is preserved when you rotate the triangle.

2.) It was clear that triangle A'B'C' is dilated form ABC, meaning the angles will be the same.

3.) The rules for dilation only change the length of the triangle not the angles.
