If a quad is a rhombus, then it is a rectangle. If the opposite sides of a quadrilateral are parallel, then it is a parallelogram. A quadrilateral is a parallelogram if one pair of opposite sides is congruent. If a quadrilateral has one pair of parallel sides, then it is a parallelogram.

Yes if diagonals of a parallelogram are equal then it is a rectangle. ... Since PQRS is a parallelogram and one of its interior angles is 90º, PQRS is a rectangle.

A parallelogram is a quadrilateral with opposite sides parallel. ... A rectangle is a parallelogram but with all four interior angles fixed at 90° A rhombus is a parallelogram but with all four sides equal in length. A square is a parallelogram but with all sides equal in length and all interior angles 90°

A quadrilateral MUST be a parallelogram if it has both pairs of its opposite sides parallel. ... A quadrilateral MUST be a parallelogram if it has both pairs of its opposite angles congruent (or equal in measure). A quadrilateral MUST be a parallelogram if it has both diagonals bisecting each other.

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.

A parallelogram has four sides total and two pairs of sides that are parallel. A square is the parallelogram that has four equal sides. ... The opposite sides are parallel, but the corners do not form right angles. A diamond shape is a good example of a rhombus.

If the diagonals of a parallelogram are equal, then show that it is a rectangle. its interior angles is 900. Since ABCD is a parallelogram and one of its interior angles is 900, ABCD is a rectangle.

A square must have opposite sides parallel, all sides congruent, and four right angles. We could also say that a rectangle is a parallelogram with four right angles, while a square is a parallelogram with four congruent sides and four right angles. But wait! ... A square IS a rectangle.

Properties of a Rectangle The diagonals are congruent and bisect each other (divide each other equally). Opposite angles formed at the point where diagonals meet are congruent. A rectangle is a special type of parallelogram whose angles are right.

Now, a rectangle is a special type of parallelogram all the sides of which make right angles. Hence the width of the rectangle, is, effectively the perpendicular from its base to its top. ... You can call a rectangles length "base" and its width "height" if you want.

In a parallelogram if two diagonals are equal, then the parallelogram is a rectangle.So, ABCD is a rectangle.It is known that each interior angle of a rectangle is 90 degree. Since ABC is an interior angle of rectangle ABCD, so measure of angle ABC is 90 degree.

A Parallelogram is a flat shape with opposite sides parallel and equal in length. Angles "a" and "b" add up to 180°, so they are supplementary angles. NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
