Question

Which statement is true?
A) All trapezoids are similar.
B) All rectangles are squares.
C) All squares are parallelograms.
D) All equilateral triangles are congruent.

Answer 1

I believe the answer should be D, since equilateral triangles means that all the sides are the same length, and congruent means two figures having the same length, and the same shape.
Hope this helps!
