If all of the diagonals are drawn from a vertex of an octagon how many triangles are formed?
5 triangles are formed.
How many triangles can be formed by using any three points as their vertices?
The answer depends on how many points there are and how many triplets are non-collinear.
What kind of triangle are formed if the rectangle is divided diagonally into two?
You would get two right-angled triangles.
How many right triangles can be formed by drawing all three lines of symmetry in an equilateral triangle?
Six
How many triangles can you fit in a regular polygon?
The number of triangles that can be formed within a regular polygon depends on the number of sides the polygon has. For an n-sided polygon, where n is greater than or equal to 3, you can form n-2 triangles within the polygon. This is because each triangle is formed by connecting one vertex to any other two non-adjacent vertices. So, for example, in a regular pentagon (5-sided polygon), you can form 5-2 = 3 triangles.
How many different triangles can be formed using three vertices of a hexagon as vertices of a triangle?
30, its a combination. C(6,3) because there are six vertices of a hexagon and three vertices of a triangle
How many triangles can be formed in a 15 sided polygon when one of its vertices is joined to the other vertices?
13 triangles will be formed
How many triangles can be formed with 5 vertices?
10 triangles....
Triangles formed by joining the vertices of a decagon?
Eight triangles.
How many triangles are formed in a octagon?
6
If all of the diagonals are drawn from a vertex of an octagon how many triangles are formed?
5 triangles are formed.
What is the maximum number of triangle that can be formed in a regular octagon by drawing all posaible diagonals from a single vertex Expain your response?
6 triangles because there are 180 degrees in a triangle and 6*180 = 1080 degrees which is the sum of the angles in octagon when added up.
What shape can be formed by cutting a triangle off of each of the four corners of a rectangle?
An 8 sided octagon or a 4 sided rhombus can be formed depending on the size of the triangles cut from each corner.
What triangles are formed when you cut an equilateral triangle?
An isosceles triangle
How many triangles in a 13 sided polygon?
To determine the number of triangles that can be formed within a 13-sided polygon, we can use the formula nC3, where n is the number of vertices in the polygon. In this case, n = 13. So, 13C3 = 286 triangles can be formed within a 13-sided polygon.
If all of the diagonals are drawn from a vertex of an n-gon how many triangles are formed?
If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed
How man triangles are in a 18-gon?
To find the number of triangles that can be formed in an 18-gon, you can use the formula for combinations: ( C(n, k) ), where ( n ) is the number of vertices and ( k ) is the number of vertices needed to form a triangle (which is 3). For an 18-gon, this is calculated as ( C(18, 3) = \frac{18!}{3!(18-3)!} = \frac{18 \times 17 \times 16}{3 \times 2 \times 1} = 816 ). Therefore, there are 816 triangles that can be formed from the vertices of an 18-gon.
