Missing angles and lengths

In this lesson, we will be studying angles. We will use algebra and bar models to represent problems and calculate missing angles.

In this lesson, we will compare and classify triangles, looking at how to recognise the different types of triangles and the sum of the angles in a triangle.

In this lesson, we will classify different types of quadrilateral and learn about the sum of their internal angles.

In this lesson, we will represent the angles in a triangle pictorially and algebraically before learning how to calculate missing angles.

In this lesson, we will represent the angles in a quadrilateral pictorially and algebraically before learning how to calculate missing angles.
