Math Problem Statement
Mr. Jack used similar triangles to make a design.
Which statement about the triangles in the design must be true?
Select TWO correct answers.
A.They are the same shape, but not necessarily the same size.
B.They are the same size but different shapes.
C.They have corresponding sides that are congruent.
D.They are the same size and shape.
E.They have corresponding angles that are congruent.
Solution
The concept of similar triangles means that they are the same shape, but not necessarily the same size. Additionally, corresponding angles in similar triangles are always congruent, and their corresponding sides are proportional, but not necessarily congruent.
Therefore, the TWO correct answers are:
- A. They are the same shape, but not necessarily the same size.
- E. They have corresponding angles that are congruent.
