By the end of this unit, students will be able to apply the properties of angles at a point to calculate unknown angles.
Curriculum Alignment: Key Stage 3: Geometry and Measures
- derive and illustrate properties of triangles, quadrilaterals, circles, and other plane figures [for example, equal lengths and angles] using appropriate language and technologies
- derive and use the sum of angles in a triangle and use it to deduce the angle sum in any polygon, and to derive properties of regular polygons
