The number of triangles that can be formed using five points in a plane depends on the arrangement of those points. If the five points are in general position (no three points are collinear), the number of triangles can be calculated using the combination formula ( \binom{n}{r} ), where ( n ) is the total number of points and ( r ) is the number of points to choose. Therefore, the number of triangles formed by five points is ( \binom{5}{3} = 10 ). If some points are collinear, the number of triangles would be fewer.

Why can all five sides figures be made from three triangles?
Because the sum of the sides of three triangles is nine... Placing three triangles together so they all touch effectively removes four of the total number of sides - leaving five.
What is a pentagon with five triangles called as a net?
A pentagon with five triangles as a net is commonly referred to as a "triangular prism" net. In this configuration, the pentagon serves as the base, while the five triangles represent the lateral faces that connect to the base. When folded, these triangles form the sides of the prism, enclosing a three-dimensional space.
How do you make five triangles out of nine matchsticks that are laid out in the form of four triangles by only moving two of the match?
To create five triangles from the four triangles formed by nine matchsticks, you can move two matchsticks from one of the triangles to create a new triangle. Specifically, remove one matchstick from the base of one triangle and one from the apex of an adjacent triangle, and reposition them to form an additional triangle that shares sides with the existing triangles. This reconfiguration will yield a total of five triangles.

How many triangles can be made from five points?
The geometric shape formed by connecting the perimeter of five points is a pentagon. Its basic construction is that of three triangles with one triangle in the middle sharing two of its sides with a base line of the other two triangles. The maximum number of triangles that can be created, if you count only those triangles that are formed by line segments between each of the five points, are ten (10).
Can a five sided figure be made from tree triangles and why?
Yes, because the number of triangles that are formed in a polygon is 2 less than the numbers of its sides.
How many triangles in an undecagon?
There are 11 triangles in an undecagon. The number of sides of a polygon is the number of triangles it has.
How many triangles are there in a heptagon?
seven There are five triangles in a heptagon. In ay convex polygon the triangles are two less than the sides. So a heptagon which has 7 sides, contains 5 triangles.

What is the pattern linking the number of sides to the number of triangles?
number of sides minus 2 = number of interior triangles
