Which of the following(s) is true of a rectangle? a. it is also a square b. the sum of its angles measures is 360 c. it has four congruent angles d. it has four congruent sides

Explanation:

Let's take a look at all of our options.

A. it is also a square

A rectangle is NOT always a square because a square has congruent sides, so that means all four of its sides are always equal.A rectangle can be a square but it can also not be a square, so therefore A cannot be an option because it is not always true about a rectangle.

B. the sum of its angle measures is 360

This is true because every quadrilateral's angle measures will add up to 360 degrees, no matter what. This is like how a triangle's angle measures always add up to 180 degrees.B is an option because it is an ALWAYS true statement.

C. it has four congruent angles

A rectangle always has 90 degree angles, giving it its shape.Since a rectangle always has the same-degree angles, that means that it DOES have four congruent angles.C is also an option because it is always true.

D. it has four congruent sides

A rectangle does not ALWAYS have four congruent sides. Say for example a rectangle has a longer length than its width. A square has four congruent sides, but a rectangle is not always a square, therefore this option is not applicable for a rectangle since it is not always true.Answers:

B and C are always true of a rectangle.
