Splet27. mar. 2007 · The measure of an interior angle of a regular polygon is 135 degrees. Find the number of sides in the polygon. This is what I tried: 180 (x-2)=135 [Interior Angle Sum Theorem] x-2=.75 x=2.75 That can't be right though. Help? Not sure about your formula. Number of sides = 360/ (180-interior angle) so Number of sides = 360/ (180-135) = … SpletThe exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles. Remember that the two non-adjacent interior angles opposite the exterior angle are sometimes referred to as remote interior angles. For example, in triangle ABC above; ⇒ d = b + a. ⇒ e ...
SpletTo find the measure of one interior angle, we take that formula and divide by the number of sides n: (n – 2) * 180 / n. What is the measure of one of the interior angles of a regular polygon if the measure of each exterior angle is 20? Each exterior angle of a regular polygon = 20 deg. So the polygon has 360/20 = 18 sides. Splet22. jul. 2024 · Sum of interior angle of any polygon = 180* (n- 2 ) Here, n= number of sides. Sum of interior angles of regular octagon = 180 * ( 8-2) = 180 * 6 = 1080° In regular octagon, all the angles are congruent, So, measure of an interior angle of regular octagon = 1080/8 = 135° Sum of interior angles of regular hexagon = 180 * ( 6-2) = 180*4 = 720°
