Sum of Interior Angles of a Pentagon
The sum of the exterior angles of any polygon is 360. Four congruent sides and interior angles are 90 - QED. Image Result For Polygon Interior Angles Regular Polygon Exterior Angles Math Charts Y 1 a 1 x b 1 and y 2 a 2 x b 2 the graphs of the functions will be perpendicular and will make four right angles where the lines intersect if a 1 a 2 1. . Interior Angles The Interior Angle and Exterior Angle are measured from the same line so they add up to 180. How many sides does it have. What is the perimeter of the pentagon. Investigation - Nature of roots of quadratic equations. The opposite of a regular polygon. Thus defining two linear functions. Thus the sum of the interior angles of a pentagon is 540. We know that the sum of the interior angles of a polygon of n sides n 2 180. Therefore to find the sum of the interior angles of an irregular polygon we use the formula the same formula as used for regular p...
