Ask the learners what type of triangle was formed. Tell them to experiment with all of the blocks to find other sets of three that form right-angled triangles. Some students may connect the previous tables and try 52, 122, and 132 as an example. They may also discover that 32, 42, and 52 (smaller proportional version of 62, 82, and 102) and 92, 122, and 152 create right angled triangles.

A key point is that right-angled triangles are formed when the sum of squares of the two shortest sides equals the square of the longest side. Non-right-angled triangles are formed in any other case.
