What is the measure of an interior angle of a regular octagon?
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° SpletTherefore, every exterior angle measures 360º / 6 = 60º. Now, as we can see in the figure the interior and exterior angles of the hexagon are in a straight line, that is, they form a … franke white goods
How to find the individual measurement of an interior angle for a ...
SpletAs we know, the exterior angle plus the interior angle adds up to 180°, so the missing angles moving clockwise from the top are: 180 – 71.4 = 108.6° 180 – 56.4 = 123.6° SpletHence, the measure of each interior angle of a regular pentagon is given by the below formula. Measure of each interior angle = [ (n – 2) × 180°]/n = 540°/5 = 108°. Here, n = Number of sides Read more:- Types Of Polygon Area Of Polygon Perimeter Of Polygons Congruence Of Triangles Class 9 Exterior Angle of a Regular Pentagon SpletFind the measure of each interior angle of a regular polygon of 9 sides.
