Precession and the pentagram
Angle BCD = 108°, so its supplement, angle HCD = 72°. Since the five triangles forming pentagram FGHIJ are isosceles, their base angles are congruent, so angle HDC = 72°. Also, the sum of the interior angles of a triangle is 180°, so angle H = 180° - (72° + 72°) = 36°. The same is true for angles F, G, and I, which also have measures of 36°.

Lets count the number of triangles where side of the pentagon is one of the side of the triangle, for each one such side there are 6 triangles. but two of triangle has other side of the pentagon, those will be counted twice so we will count only one triangle for each side, so for five sides, total 5*5 = 25 such triangles.

You can make a pentagram by first drawing a pentagon, then extending the edges. Or by drawing lines from corner to corner inside a pentagon. Polygon In fact a Pentagram is a special type of polygon called a "star polygon". Ratios The regular pentagram has a special number hidden inside called the Golden Ratio, which equals approximately 1.618

If we divide a pentagon into triangles as in the figure on the left below, the pentagon is made up of 3 triangles, so the angle sum is 180 + 180 + 180 = 3*180 = 540 degrees. However, the non-convex pentagon on the right is a trickier case.

A pentagram can either be formed by connecting alternate vertices of a pentagon or by creating five triangles outside the pentagon. There are two types of pentagrams - regular and irregular pentagrams. Let's learn more about it in detail. Pentagram Definition A pentagram is the shape of a five-pointed star polygon.

LEVEL 16 How many triangles are in a Pentagram? Brain Out ANSWER
Because each side of the pentagonal star has the same length, there are ten triangles that are isosceles in shape. Five of these ten are examples of triangles with obtuse angles. Therefore, a pentagram has a total of ten triangles, all of which are isosceles.
How many triangles are in a Pentagram? YouTube
Natural Perfection! A pentagram is a symmetric five pointed star, meaning that it fits perfectly inside a pentagon. The lengths of the various lines and segments between the points where they cross each other correspond to the Golden Ratio. Even many of the triangles within the pentagram are in the golden ratio!
