MT Triangles

In this activity, a right triangle is drawn with base and height taken from the MT puzzle.

What do you notice about shapes and sizes of the triangles drawn?

Figures that have the same shape (even if their sizes are different) are called similar. What have you discovered about similar triangles?

This activity is based on the paper version of MT Puzzles which was co-invented by Dr. Dor Abrahamson and Professor Karen C. Fuson.
