How many polygons do you need to construct a pentagonal pyramid And what kind of polygons?

What are the sizes of angles in a pentgonal pyramid?
A regular pentagonal pyramid is composed of five equilateral triangles and one regular pentagon. Each equilateral triangle has three angles of 60 degrees each. The regular pentagon has five internal angles of 108 degrees each.
What is a solid that has five triangles and one pentagon?
A pentagonal pyramid.
What has 6 faces but only one is a pentagon?
A pentagonal pyramid. It has a pentagon for the base then five triangles going to a point.
What shape has 1 pentagon and 5 triangles?
A shape with one pentagon and five triangles can be visualized as a pentagonal pyramid. In this configuration, the pentagon serves as the base, and the five triangles converge at a single apex above the pentagon, forming the triangular faces of the pyramid. This structure combines the two types of polygons in a three-dimensional form.
What kind or kinds of polygons would you need to construct a pentagonal pyramid How many of each kind or kinds of polygons would you need?
One pentagon and five triangles.
How do you divide a pentagon in five parts?
One possible way to divide a pentagon into five parts is (assuming this is a convex pentagon) to start by placing a dot directly in the center. Then, draw a 5 lines from that center dot connecting to the 5 points around the edge of the pentagon. You should now have 5 triangles instead of 1 pentagon.
What is perimeter of the pentagon?
Five times the length of one of the sides.
What shape has Five sides and one right angle?
Five side is always a pentagon, but there's no pentagon that always has exactly one right angle. A regular pentagon has no right angles. An irregular pentagon can have one, two, or three right angles, or none.
What is the size of each interior angle of a regular pentagon?
The answer is 108'. There is a nice way of answering this for any regular polygon (like a square, a pentagon, a hexagon etc): first split your regular polygon into triangles by joining one vertex (point where 2 lines meet) to all other vertices. You will be left with several triangles, (eg in a pentagon 3 triangles). The interior angles of a triangle add to 180', so we can see that the interior angles of our pentagon add to 3 x 180 = 540'. And there are 5 vertices so 540/5=108', which is out answer.
How many equal sides does a pentegon have?
A pentagon may have zero, two, three, four, or five equal sides.A regular pentagon is one in which all five sides are equal.
How many angles are inside a pentagon?
There are five angles within a pentagon and in a regular one each angle is 108 degrees.
