How To Find The Measure Of One Interior Angle Of A Parallelogram. A parallelogram is a quadrilateral with two pairs of parallel sides. Since angles and are opposite interior angles they must be.
Sum of Interior Angles of a Polygon with Different Number of Sides. A parallelogram is a quadrilateral with two pairs of parallel sides. 3-21803 60 Square 4-21804 90.
A parallelogram must have equivalent opposite interior angles.
The sum of interior angles of a regular polygon and irregular polygon examples is given below. First one must be aware that the sum of the measures of the interior angles of a parallelogram is 360 degrees sum of the interior angles of a figure 180n-2 where n is the number of sides of the figure. Absin t clearly reaches its maximum where sin t 1 ie t90 degrees. Second one must know that the other two interior angles are doubles of those given here.
