Chapter 5 Angles and Trigonometry

# 5.1 Angle Properties of Triangles and Quadrilaterals

A quadrilateral is a polygon which has 4 vertices and 4 sides enclosing 4 angles and the sum of all the angles is 360Â°. While the angle sum property of a triangle theorem states that the sum of all three internal angles of a triangle is 180Â°. In this section, we learn about Angle Properties of Triangles and Quadrilaterals, parallel lines, alternating angles, corresponding angles, quadrilateral angles sum, triangle angle sum, angles sum.

If you're a student in a school/college that's based in England, you might be entitled for full access to our eLearning platform where you can access to all our tutorial videos and practice questions.

Please check with the head of Maths or deputy headteacher at your school/college to request access if they've already registered to our free pilot subscription. They can always reach us at the below email:
