Question

Which set of shapes contains members that are always similar to one another?

Answer 1

all quadilateral triangle...

Answer 2

Equilateral triangles are the set of shapes which contains member that always similar to one another.

• The equilateral triangle is basically a triangle which has three equal sides.

• Due to three equal sides,the three angles of an equilateral triangle are also equal. (Each angle is 60°)

• Now,in a set of geometrical shapes,if we take two equilateral triangles which have same length of sides. Then those two equilateral triangles will be exactly equal with each other,both in terms of sides and angles.
