An interior angle is located within the boundary of a polygon. The sum of all of the interior angles can be found using the formula S = (n - 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.

To find the measure of the interior angles, we know that the sum of all the angles is 900 degrees (from above)... And there are seven angles... So, the measure of the interior angle of a regular heptagon is about 128.57 degrees.

['A rectangle is a quadrilateral.', 'The opposite sides are parallel and equal to each other.', 'Each interior angle is equal to 90 degrees.', 'The diagonals bisect each other.', 'Both the diagonals have the same length.', 'A rectangle with side lengths a and b has the perimeter as 2a+2b units.']

If you are given one interior angle of an isosceles triangle you can find the other two. ... We know that the interior angles of all triangles add to 180°. So the two base angles must add up to 180-40, or 140°. Since the two base angles are congruent (same measure), they are each 70°.

To find the value of an internal angle within this polygon, we can just multiply the number of triangles by 180 ° , then divide by the number of internal angles, which is nine. Excellent! So the interior angle of a 9 -sided polygon is 140 ° .

2) You can use the (n – 2)*180 formula to find both the sum of the interior angles of an irregular polygon and the average measure of an angle in an irregular polygon (just divide the sum by n).

The formula for finding the sum of the interior angles of a polygon is the same, whether the polygon is regular or irregular. So you would use the formula (n-2) x 180, where n is the number of sides in the polygon.

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

For a hexagon the sum of the interior angles is thus (6–2)*180 = 4*180= 720, so each interior angle is 720/6 = 120 deg.

To find the measure of the interior angles, we know that the sum of all the angles is 540 degrees (from above)... And there are five angles... So, the measure of the interior angle of a regular pentagon is 108 degrees.

Interior Angles of a Square To find the measurement of the interior angles in a square, you divide the sum of the angles (360o) by the number of sides (4). So, 360o / 4 = 90o. All the angles in a square are equal to 90o. The sum of the angles of a square is 360 degrees.

If you are given one interior angle of an isosceles triangle you can find the other two. For example, We are given the angle at the apex as shown on the right of 40°. We know that the interior angles of all triangles add to 180°. So the two base angles must add up to 180-40, or 140°.

['The interior angles of a triangle add to 180°:a + b + c = 180°', 'Angles c and d make a straight angle, which is 180°:d + c = 180°', 'So d + c equals a + b + c:d + c = a + b + c.', 'Subtract c from both sides:d = a + b.']

To keep all the interior angles obtuse, the polygon has to be convex. If all the angles are the smallest possible whole number, they will all be 1 degree. You can finish this off, knowing that all the angles are the same (1 degree) size and that the sum is 360 degrees.
