Which figure must be a square?








A.

a quadrilateral with congruent sides








B.
a parallelogram with four congruent sides







C.
a rhombus with four right angles





D.
a quadrilateral with four right angles

Help Please

Answer 1

A square is equilateral and equiangular.

So, all the sides are the same AND all the angles are the same.

Because the sum of the angles of a quadrilateral is 360, each angle of the square has to be a right angle.

Based on that info, what do you think is the answer to your question @Awolflover1

Answer 5

I think D

Answer 6

Option D is not correct.

Answer 7

Option D has 4 right angles. But, you also must have 4 sides which are the same.

Look again at the options.

Answer 8

a rectangle?

Answer 9

No. A rectangle has right angles but does not have congruent sides unless it is also a square.

Answer 10

Answer 11

A rhombus has 4 congruent sides

Answer 12

Yes.

Answer 13

So, what if the rhombus had 4 right angles? Would it be a square?

Answer 14

No?

Answer 15

Yes, it would. Because as you said, the rhombus has 4 sides the same.

So, if it had right angles, then it would be equiangular and equilateral which would make it a square.
