A Shape Made with Two Equilateral Triangles
Join two equilateral triangles at their sides. Connect one triangle to the
other triangle on different sides.
Shapes that are the same after being rotated or flipped are counted as
one. Therefore, all shapes that are made up of two equilateral triangles
are counted as one.
A Shape Made with Three Equilateral Triangles
Add one equilateral triangle to the sides of the shape made up of two
equilateral triangles in the order shown below.
How many different shapes can be made by connecting three
equilateral triangles?
