If triangles are formed by joining the vertices of a cube then number of equilateral triangles formed is

Triangles are formed by joining vertices of a octagon then numbr of triangle

How many triangles can be formed by joining the vertices of a hexagon?

Consider an equilateral triangle of a side of unit length. A new equilateral triangle is formed by joining the mid-points of the first one, then a third equilateral triangle is formed by joining the mid-points of the second. The process is continued. The sum perimeter of all triangles thus formed is

If a triangle is formed using the vertices of a cube then the probability that the triangle is equilateral is

Write the type of triangle formed by joining the midpoints of the sides of an equilateral triangle.

Triangles are formed by joining vertices of an octagon. Any one of those triangle is selected at random. What is the probability that the selected triangle has no side common with the octagon?

How many right angled triangles can be formed by joining the vertices of a cuboid ?
