LASD: Proving Triangles Congruent, Part 1
You are given triangle ABC in quadrant 2, and a partial image of ABC in quadrant 1. What parts of the triangle are you given in the partial image?
a. Use the "Segment with Given Length" tool to complete the image. b. Use one transformation to map the original triangle onto the image.
c. Describe which transformation you used. d. Are the original triangle and the image congruent? d. Can we conclude that any two triangles with a comparable set of starting parts are congruent? Explain your reasoning.
