Students begin by investigating the sum of the angles in different types of triangles.
As learning progresses they apply the sum of angles in a triangle and other geometrical properties to solve more challenging and complex problems.
Differentiated Learning Objectives
- All students should be able to calculate the remaining angle in a scalene and right angled triangle when given the two.
- Most students should be able to use the properties of triangles to calculate angles in isosceles and equilateral triangles when given one.
- Some students should be able to calculate angles in compound shapes involving multiple types of triangle.
