Question

Give reason: Squares, rectangles, parallelograms are all quadrilaterals.

Answer 1

Step 1: Explain Square, Rectangles, Parallelograms

We also know that a square is a geometric figure that has four equal sides and all of its angles are $90°$.

We know that a rectangle is a geometric figure that has two opposite pairs of equal sides and all of its angles are $90°$.

We know that a parallelogram is a geometric figure that has two opposite pairs of parallel sides.

Step 2: Explain Quadrilateral

We know that a quadrilateral is a geometric figure that has four sides.

Therefore, all squares, rectangles, and parallelograms have four sides.

Hence, squares, rectangles, and parallelograms are all quadrilaterals.
