Use should include the following concepts:
- Triangles are used as a strong shape in construction.
- The Pythagorean theorem is used for right triangles.
- The hypotenuse is the side of the triangle that does not have a right angle.
- The square root of the hypotenuse is equal to the square root of the sum of the squares of the other two sides (a² + b² = √c²).
