Repeaters, Vedantu They are formed on the outer part, that is, the exterior of the angle. This confirms that the exterior angles, taken one per vertex, add to 360° The sum of exterior angles - watch out! The diagonals of a trapezoid are congruent. Opposites sides of a parallelogram are parallel and congruent. Parallelograms are the four sided closed plane geometric shapes in which the opposite sides are equal and parallel. It has only two dimensions namely length and width. The angle enclosed within the adjacent side is called the interior angle and the outer angle is called the exterior angle. Quadrilaterals are 2D shapes with four sides and angles. Q. • Kite is a quadrilateral which has two pairs of equal consecutive sides. An additional solution to the one given by Alan P is using the fact that the sum of the interior angles of a parallelogram is 360°.

Download the set (3 Worksheets) Solve for x (diagonal) This bundle of printable worksheets features parallelograms with one or two diagonals. 92. Opposite sides are equal lengths. Since the parallelogram has 2 triangles, its area is twice the area of the triangle. Since opposite sides of a parallelogram are congruent, its perimeter can be written as the sum of all the four sides in terms of length and width as: The Perimeter of a Parallelogram = 2 (L + B). Sum of any two interior adjacent angles of a parallelogram is a straight angle (i.e. A quadrilateral is a closed geometric shape which has 4 vertices, 4 sides and hence 4 angles that lie on the same plane. Identify whether the given quadrilateral is a parallelogram or not. Examples.
