What fractional part is polygons?
a lml told me to vertex it
A base angle of an isosceles triangle is 9 degrees more than the vertex angle Find the vertex angle?
let the vertex angle be x degrees, then the base angle is x + 9 degrees. Since in a triangle the sum of the angle is 180 degrees, and the base angles in an isosceles triangle are congruent, we have: x + 2(x + 9) = 180 x + 2x + 18 = 180 3x + 18 = 180 subtract 18 to both sides 3x = 162 divide by 3 to both sides x = 54 Thus the vertex angle is 54 degrees.
What shape has 15 edges and 9 vertex?
Not sure there is such a shape. In order to satisfy the Euler characteristics, the shape must have 8 faces and so is an octahedron. But there seems to be no octahedron with 9 vertices.
How many vertices does a nonagonal pyramid have?
Ah, a nonagonal pyramid is a beautiful shape! It has 9 vertices, one at the top where all the edges meet, and 8 at the base where the sides come together. Each vertex is like a little friend, all coming together to create a wonderful geometric masterpiece.
How many vertices does an octagonal pyramid have?
An octagonal pyramid has 9 vertices. The base of this shape is an octagon, which will give it 8 vertices when the triangles that form the sides are considered. Those triangles will lead up to the apex (top) of the pyramid, and that will be the 9th vertex.
