It can be, if all the vertices of the pentagon are joined to its centre. But if they are joined to any other point, it will not be.

What are the three types of polygons that can be the faces of a Platonic solid?
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
How many triangles can be made in an octagon by drawing all the diagonals from one vertex?
You Can Get 6 triangles
Find the area of the largest square incribed in a circle?
A circle of radius, r, has area pi r2. The largest square inside it is made up of four isosceles triangles whose equal sides are of length, r, and thus has area 1/2 r2. Thus the area of the contained square is 2 r2.
How can you tell the difference between the net for a triangular prism and the net fora triangular pyramid?
A net for a triangular pyramid is made out of 4 triangles. A net for a triangular prism is made out of 3 rectangles and 2 triangles.
A right pentagonal prism is made of seven angles?
There are at least 30 angles between edges in a right pentagonal prism. If the entlgon is regular there are two different vlues for these angles; 90 and 108 degrees.
What shapes make up a pentagon?
A pentagon is a five sided regular polygon; as such, it is made up of five line segments. If you wanted to, you could also construct a pentagon out of five triangles that fit together much like a pie.The shapes that make a pentagon is triangles, rhombuses and diamonds. Dummy next time answer the question and stop giving a meaning when that was not asked for or that wasn't the question
What is the formula to determine how many parallelograms there are in an isosceles triangle made up of smaller isosceles triangles of the same size?
An isosceles triangle can be divided into 4 smaller, identical isosceles triangles. Each of these can then be divided into 4, and each of them ... So, the answer to the question is infinitely many.
Are pyramids made up from equilateral triangles?
The Great Pyramids at Giza are, but the Meso-Americans were truncated.
What shape is made up from 4 triangles?
It would depend on the triangles, but assuming they were equilateral or isosceles, a trapezoid if alternated in a line.
What is the name of a quadrilateral made from two identical isosceles triangles?
In general, a parallelogram. But if the triangles are joined along their odd side, a rhombus.
What are the three types of polygons that can be the faces of a Platonic solid?

What is the formula to determine how many parallelograms there are in an isosceles triangle made up of 9 smaller but equally sized isosceles triangles?
There are normally no parallelograms within an isosceles triangle unless you put them there yourself.
Can all 4 sided shape be made by two right angled triangles?
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
How many triangles can a 20-gon be made into?
20 isosceles triangles with each base being a side of the 20-gon, and the opposite vertices at the center of the polygon.
Does a pentagon have perpendicular sides?
A regular pentagon does not have any perpendicular sides. A pentagon is made up of five sides. An irregular pentagon which has sides that are not equal may have a perpendicular side.
What shape is made out of two congruent triangles?
If you have 2 EQUILATERAL triangles, and you stack them on their respective hypotenuses, the result: SQUARE. If you have 2 ISOSCELES triangles, and you stack them on their respective hypotenuses, the result: RECTANGLE. If you have 2 OBTUSE triangles, and you stack them on their respective hypotenuses, the result: PARALLELOGRAM.
Can all 5 sided figures be made from 3 triangles and why?
Yes because there are 540 degrees in a pentagon and 180 degrees in a triangle so 540/180 = 3 triangles.
