What is a 70 sided shape called?

heptacontagonIn geometry, a heptacontagon (or hebdomecontagon from Ancient Greek ἑβδομήκοντα, seventy) or 70-gon is a seventy-sided polygon. The sum of any heptacontagon’s interior angles is 12240 degrees.

What is the sum of the exterior angles of a polygon with 100 sides?

360∘Since we know that sum of exterior angles of a convex polygon is 360∘ . so the sum of the exterior angle of the convex polygon with 100 sides is 360∘ .

What is the formula of exterior angles?

The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.

What is the sum of the 3 exterior angles of a triangle?

One can also consider the sum of all three exterior angles, that equals to 360° in the Euclidean case (as for any convex polygon), is less than 360° in the spherical case, and is greater than 360° in the hyperbolic case.

What is the exterior angle sum of any polygon?

If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.

What is the sum of exterior angles of a convex polygon?

Sal demonstrates how the the sum of the exterior angles of a convex polygon is 360 degrees.

What is the sum of the exterior angles of a 17 sided polygon?

360°The sum of the interior angles of a 17-sided convex polygon is 2700°, and the sum of the exterior angles is 360°.

What is the sum of interior angles of a 15 sided polygon?

Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be 13 × 180 = 2340 degrees.
