Is parallelogram a rectangle?

A rectangle is a quadrilateral in which all angles are right angles. A rectangle is a parallelogram, so its opposite sides are equal. The diagonals of a rectangle are equal and bisect each other.

Are all parallelograms rectangles yes or no?

All rectangles are parallelograms, but not all parallelograms are rectangles. And all of these shapes are quadrilaterals. The diagram below illustrates the relationship between the different types of quadrilaterals.

Is a triangle a parallelogram?

A triangle is a parallelogram. ... Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms.

Is rectangle a rhombus?

Explanation: A rectangle is a parallelogram with all its interior angles being 90 degrees. A rhombus is a parallelogram with all its sides equal. This means that for a rectangle to be a rhombus, its sides must be equal.

Why is a rhombus not a square?

How is square different from rhombus? A square and a rhombus both have sides equal in length. But square has all its angles equal to 90 degrees, but a rhombus only has its opposite angles equal.

How do you know a parallelogram is not a rectangle?

Special Quadrilaterals

A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides.

Why is every parallelogram not a rectangle?

A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. A rectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides. ... This is not true for all parallelograms since isn't necessary that any of the angles is 90°.

Which shape is a parallelogram?

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

Can 2 right triangles make a parallelogram?

Parallelogram Theorem #1 Converse: If each of the diagonals of a quadrilateral divide the quadrilateral into two congruent triangles, then the quadrilateral is a parallelogram.

Is a square always a parallelogram?

A square is a parallelogram. This is always true. Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. ... Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms.
