Question

If wxyz is a square, which statements must be true?

1) w is a right angle.
2) 80
3) 60
4) 70

Answer 1

In a square wxyz, the angle w must be a right angle, and the numbers 80, 60, and 70 do not represent properties of a square if they imply angle measurements.

Step-by-step explanation:

If wxyz is a square, certain statements about the properties of a square must be true. As a reminder, a square is a quadrilateral with four equal sides and four right angles. Therefore, we can deduce the following:

1. w is a right angle. This is because all angles in a square are right angles (90 degrees).
2. It isn’t clear what the numbers 80, 60, 70 refer to without context, but they do not represent properties of a square if they are angle measures, since all angles in a square are 90 degrees.
