question 16
pick the properties of a square. (pick all that apply)
only one set of parallel sides.
two pairs of parallel sides.
two pairs of sides of equal length.
four sides of equal length.
four angles of equal measure.
all four angles are right angles.
it may contain a right angle.

Explanation:

A square is a special type of quadrilateral. By definition:

• It has two pairs of parallel sides (so the option "Only one set of parallel sides" is wrong).
• All four sides are of equal length (so "Two pairs of sides of equal length" is not the most accurate description for a square, while "Four sides of equal length" is correct).
• All four angles are right - angles (so "Four angles of equal measure" is correct as all right - angles are equal, and "All four angles are right angles" is also correct. The option "It may contain a right angle" is wrong because it must have right - angles, not just may).

Answer:

B. Two pairs of parallel sides, D. Four sides of equal length, E. Four angles of equal measure, F. All four angles are right angles.
