GCSE Maths - Types of Triangle #100

The video tutorial covers different types of triangles: equilateral, isosceles, right-angled, and scalene. It explains that all triangles have three straight sides. Equilateral triangles have equal sides and angles, with three lines of symmetry. Isosceles triangles have two equal sides and angles, with one line of symmetry. Right-angled triangles have a 90° angle, and if isosceles, one line of symmetry. Scalene triangles have all sides and angles different, with no symmetry.

What are the key characteristics of an equilateral triangle?

What is the significance of symmetry in triangles, and how does it vary among different types?

How can you identify an isosceles triangle?

What distinguishes a right-angled triangle from other types of triangles?

Describe the properties of a scalene triangle.
