Angles in Triangles and Quadrilaterals

This Angles in Triangles and Quadrilaterals assessment also includes:

This short video show viewers how to connect the sum of the angles in a triangle to other angle measurements. Pupils determine the missing measures for angles involved with triangles and quadrilaterals. Class members then must explain their reasoning on several of the problems.
