Opposite sides are equal lengths. If the opposite sides are equal, obviously they will be parallel too. Since, it is a regular polygon, measure of each exterior angle =          360°           Number of sides 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). 1. Algebra 2. Sum of any two interior adjacent angles of a parallelogram is a straight angle (i.e. To find the measure of one angle divide the sum by n (the number of sides or angles). The important properties of parallelograms to know are: Opposite sides of parallelogram are equal (AB = DC). 100. The corresponding sum of the exterior and interior angle formed on the same side = 180°. The properties of quadrilaterals are: All the quadrilaterals have 4 vertices, 4 sides and 4 angles. PARALLELOGRAMS We begin with parallelograms, because we will be using the results about parallelograms when discussing the other figures. A quadrilateral is a type of a polygon. The opposite sides of a parallelogram are: Congruent. If we observe a convex polygon, then the sum of the exterior angle present at each vertex will be 360°. So the number of sides of the polygon = 360°/15° = 24 ... (As, a ll parallelograms have a pair of parallel sides). If we have a regular polygon of n sides, the measure of each exterior angle. So your statement is not true for a square, rectangle, parallelogram, lots of other polygons. Parallelograms are the four sided closed plane geometric shapes in which the opposite sides are equal and parallel. A quadrilateral is a closed geometric shape which has 4 vertices, 4 sides and hence 4 angles that lie on the same plane. It looks like magic, but the geometric reason for this is actually simple: to move around these shapes, you are making one complete rotation, or turn, of 360°. (180(n – 2))}, N = 180n − 180(n – 2)     N = 180n − 180n + 360N = 360. A parallelogram is one of the types of quadrilaterals.
