Question

which statements about squares and equilateral triangles are true?
choose 2 answers:
a both shapes have all sides of equal length.
b both shapes have all angles of equal measure.
c both shapes have right angles.

Explanation:

• For option A: A square has 4 equal - length sides, and an equilateral triangle has 3 equal - length sides. So both have all sides of equal length.
• For option B: In a square, each angle is \(90^{\circ}\), so all angles are equal. In an equilateral triangle, each angle is \(60^{\circ}\), so all angles are equal.
• For option C: An equilateral triangle has angles of \(60^{\circ}\) and no right angles (\(90^{\circ}\) angles), while a square has right angles. So this statement is false.

Answer:

A. Both shapes have all sides of equal length, B. Both shapes have all angles of equal measure
