Why the sum of angles in triangle is 180 degree?
Formula for finding the total sum of interior angles of any polygon is: (number of sides-2)*180 A triangle has 3 sides. (3-2)*180 = 180 degrees
What is the number of sides when the interior angle is 180 degrees?
A shape has three sides if its interior angles add up to equal 180 degrees.
What is the degrees for an angle of a regular octagon?
The sum of angles in degree = 180(n - 2), where n is the number of sides of the regular polygon. The sum of angles in degree = 180(n - 2); n = 8 The sum of angles in degree = 180(8 - 2) = 180(6) = 1,080 Angle in degree = (The sum of angles in degree)/n Angle in degree = (1,080)/8 = 135 Thus, in a regular octagon, the degree of an angle is 135.
What is the formula that tells you the degree the angles add up to?
The interior angles of a polygon with N sides sum to (N - 2)*180 degrees.
What do the angles add upto on a 5 sided shape?
Assume each side is a straight line segment. With 3 sides you can make 1 triangle with a sum of interior angles = 180°. With 4 sides you can make 2 triangles with a sum of interior angles = 2 x 180° = 360°. With 5 sides you can make 3 triangles with a sum of interior angles = 3 x 180° = 540°.
