- Introduce the hypotenuse-leg theorem (HL theorem). Have students find measures of segments, algebraically, given the triangles are congruent by the HL theorem.
- Show students multiple sets of triangles where at least two overlap and show the students how to separate and identify parts that they share (have in common).
- Allow additional time for design, if necessary.
