Identify Quadrilaterals Worksheets
How to Identify Quadrilaterals - Quadrilaterals are polygons that have four sides. There are different types of quadrilaterals; below, we have discussed the commonly known quadrilaterals. A parallelogram is a quadrilateral that has both pairs of opposite sides parallel. Its opposite sides and angles are congruent. Its diagonals bisect each other, and adjacent angles are supplementary. A rectangle is a quadrilateral that has all four angles as right-angles. The diagonals of a rectangle are congruent. Also, all parallelograms and quadrilaterals are rectangles, but not all quadrilaterals and parallelograms are rectangles. A rhombus is a quadrilateral with all four congruent sides. The diagonals of a rhombus intersect at the right angles. A square is a parallelogram with all four congruent sides and right angles. A trapezoid is a quadrilateral with exactly one pair of parallel sides. A quadrilateral with one pair of parallel sides is known as the trapezoid. An isosceles trapezoid is the one that has congruent non-parallel sides. A kite is a quadrilateral that has two pairs of adjacent congruent sides.
