Hence, find the size of each interior angle of a regular heptagon.
Answers
Step-by-step explanation:
In heptagon, the sum of the interior angles is equal to 900 degrees. The sum of exterior angles of a heptagon is 360 degrees. For regular heptagon, the measure of the interior angle is about 128.57 degrees.
Answer:
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 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.
Step-by-step explanation:
To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.
