Angles of a Triangle
Objective
Students will inductively discover the rules of a triangle's angles.
Steps
- Students try to create the biggest possible angle inside of a triangle.
- They look for triangles with one or more right angles.
- Then they add up three angles, trying to find the largest and smallest sums possible.
- Students try to create triangles with two and three congruent angles.
- We close by posing the question: how are angles and sides related?
