What is the sum of the interior angles of an dodecahedron?
180 degrees
How much is the sum of all the angles in a right triangle?
The sum of the angles in all triangles (right, isosceles, scalene, and equilateral) in the Euclidean plane is 180 degrees or pi.
What is the sum of the angles of a 14-gon?
Sum of exterior angles: 360 degrees Sum of interior angles: 2160
What is the sum of the exterior angles of a undecagon?
All polygons, including an undecagon (11-sided figure) have a sum of exterior angles of 360 degrees.
Why do you subtract 2 from n to find the sum of interior angles?
This has to do with the way in which the sum of the angles is derived. First you select a point inside the polygon and then join that point to each of the vertices. For a polygon with n sides, this gives rise to n triangles. The sum of the 3 angles of any triangle is 180 degrees. So the sum of the angles of all the triangles is n*180 degrees. Now, the "outer" angles of these triangles correspond to the interior angles of the polygon. But the sum also includes the angles formed arounf the central point. The sum of all the angles around this central point is 360 degrees. This is not part of the sum of the interior angles of the polygon and so must be subtracted. Thus, the interior angles of a polygon sum to n*180 - 360 degrees or 180*(n- 2) degrees.
What is the sum of the interior angles of an dodecahedron?
180 degrees
What is the sum of the measures of the interior angles for a regular dodecahedron?
180
How would you describe the face on an dodecahedron?
I assume you mean a regular dodecahedron. A regular dodecahedron has twelve faces, each of which are regular* pentagons. *(all sides are congruent, all angles are congruent)
How many angles does a dodecahedron have?
A dodecahedron can have 8 to 20 vertices.
Does a dodecahedron have 90 degree angles in the base?
Only the irregular dodecahedron because regular dodecahedron do not have 90 degrees on base.
What is the sum of angles in a six sided shape?
The sum of all the exterior angles is 360 degrees. The sum of all the interior angles is 720 degrees.
What is the sum of all the angles of a triangle?
The sum of all of the angles of a triangle will ALWAYS be 180 degrees.
What is the sum of the measures of the exterior angles of a polygon?
If you multiply 360 by the number of angles in the polygon and then subtract the sum of all the interior angles you will end up with the sum of all the exterior angles of the polygon.
Do all triangles have the same sum of their angles?
Yes, all triangles have the sum of their angles as 180 degrees.
The formula for finding the sum of the angles of a polygon?
The formula for finding the sum of all angles of a polygon is: N = number of sides (N-2)180 = The sum of all angles
In a quadrilateral the sum of all four angles equals?
In a quadrilateral the sum of all four angles equals 360º.
What is the value of the sum of the angles of all 3 angles of any triangle?
The sum of all the angles in a triangle always adds up to 180 degrees.
