What shape has an interior of 1080?
octagon An octagon is an 8 sided polygon with interior angles that add to 1080 degrees.
What is the name of the polygon whose sum of the interior angles is 1080 use N 2 180?
an octagon If we are given a convex polygon with n sides and S is the sum of the measures of the interior angles then S = 180(n – 2). Find the sum of the measures of the interior angles in an octagon. Hence the sum of the measures of the interior angles in an octagon is 1080°.
How many sides have a polygon with sum of the angle 1080?
8 sides 1080° = 180(p – 2). 1080° / 180 = (p – 2). 6 = (p – 2). Hence, the polygon that has 8 sides is called an octagon.
What is the sum of 8 of the interior angles of a regular dodecagon?

What is the sum of a 8 sided polygon?
In geometry, an octagon is a polygon that has 8 sides and 8 angles. All the sides are joined end to end to form the shape of the octagon. The sum of the interior angles of an octagon is equal to 1080 degrees.
What is the sum of octagon?
1080 degrees The sum of the interior angles of an octagon is equal to 1080 degrees.
What is the sides of 1080?
The sides of a polygon if the sum of the interior is 1080° is 8.
What is the sum of angles of a polygon with one side less 1080?
Answer: The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon. … Thus, the measure of each angle is equal to the sum of its angles divided by 8. Therefore, each angle in the polygon has a measure of 1080/8 = 135 degrees.
What is the interior angle of a 8 sided shape?
Solution: A regular octagon has eight sides and eight angles. A regular octagon has all its interior angles equal in measure. Therefore, measure of each interior angle = 1080°/8 = 135°.
