Which of the following best describes a square? a. a square is equilateral. b. a square is equiangular. c. a square is equiangular and equilateral. d. a square is a parallelogram

C, a square is equiangular and equilateral.

Equilateral- Having all sides of the same length (the sides of a square are all congruent).

Equiangular- Having all angles of the same measure/degree. A square is made up of four 90° angles.

C.

Step-by-step explanation:

answer: f true

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
