Problem 1
Triangle \(ABC\) is dilated using \(D\) as the center of dilation with scale factor 2.
The image is triangle \(A’B’C’\). Clare says the 2 triangles are congruent, because their angle measures are the same. Do you agree? Explain your reasoning.
Triangle A B C, it‘s image after dilation triangle A prime B prime C prime and point D. Point D is on the right, smaller triangle A B C is in the middle and larger image triangle A prime, B prime and C prime is on the right.
