In Figure 1, there are two triangles. ... Example 1 Find the sum of the measures of the interior angles of an octagon. Since, octagon has eight sides then (𝑛 − 2) 𝑥 180º = (8-2) x 180º = 6 x 180º = 1,080º. WebA heptagon has 7 sides, so we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees. Same thing for an octagon, we take the 900 from before and add another 180, (or another triangle), getting us 1,080 degrees. So we can use this pattern to find the sum of interior angle degrees for even 1,000 sided polygons. high point stove parts
