Question

ΔABC is dilated from the origin at a scale factor of 3 to create ΔA′B′C′. Select the option that completes the statement: The triangles' corresponding angles are ________, and their corresponding sides are ________; therefore, the triangles are ________. congruent; similar; proportional congruent; proportional; similar proportional; congruent; similar proportional; similar; congruent

Answer 1

Answer: The answer is B

Explanation:

Answer 2

Answers:

congruent; proportional; similar

Explanation:

The angles are congruent because dilations do not change shapes and do not change angle sizes. However, the side lengths do change. They get 3 times bigger. This makes the sides proportional. Therefore, the triangles are similar (but not congruent).
