3 There are two equilateral triangles joined at one vertex on the graph
paper shown below. Shapes that are the same af ter being rotated or
flipped are considered the same.
Example
Joined at one vertex.
As in the example above, draw the cases where three triangles
meet at one vertex.
As in the example above, draw the cases where three triangles
meet at two vertices.
As in the example above, draw the cases where three triangles
meet at three vertices.
