Find The Sum Of The Interior Angles Of An Octagon

So the sum of the interior angles of an octagon is 1080 degrees.

Find the sum of the interior angles of an octagon. The formula for the sum of the degree measures of the interior angles of a polygon is s 180 n 2. 7th grade math ms. An octagon s internal angles add up to 1080 degrees.

Because the sum of the angles of each triangle is 180 degrees. That means that if you add up all the angles in those six triangles you ll get the total internal angle sum of the octagon. Alternate interior angles.

Find the sum of the interior angles of a nonagon. Solve for n the number of sides of the polygon in terms of s. The diagonal lines draw triangles and the interior angle measure of triangles are always.

In this case 6 x 180 1080. Sum interior angles number of sides 2 180 8 2 180 1080 the sum of the interior angles of an octagon is 1080 in a regular octagon divide by 8 for each angle 135. An octagon has 8 sides so it s sum of interior angles 180 8 2 180 6 1080 degrees.

Same side interior angles d. Sum of interior angles of any closed regular polygon is given by n 2 180 where n is number of sides so octagon s internal angle sum is 1080 and hexagon is 720. To find interior angle measurements you must divide the shape into triangles by drawing diagonal lines.

To find the sum of the interior angles of an octagon divide it up into triangles. 1 point 140 1 620 1 260 1 450 4. Sum of interior angles 180 n 2 where n is the number of sides.
