Angles, Lines And Triangles
Akopọ
Angles and lines are the starting point for all geometry. Knowing the properties of parallel lines, vertically opposite angles, and triangle types lets you find unknown angles in a single step, and every harder geometry question builds on these foundations.
You will learn to classify angles, apply the rules for intersecting and parallel lines, and use the angle properties of different triangle types. These facts appear in almost every geometry question on both papers.
Awọn Afojusun
- Distinguish between acute, obtuse, reflex and right angles
- Use angle properties of intersecting lines, parallel lines and angles on a straight line
- Understand the exterior angle of a triangle property and the angle sum of a triangle property
- Understand the terms 'isosceles', 'equilateral' and 'right-angled triangles' and the angle properties of these triangles
