Types of Triangles

This video tutorial covers the different types of triangles: right angled, equilateral, isosceles, and scalene. It explains their properties, such as angles, sides, and lines of symmetry. Right angled triangles have a 90° angle and a hypotenuse. Equilateral triangles have three equal sides and angles, each measuring 60°. Isosceles triangles have two equal sides and angles, with one line of symmetry. Scalene triangles have no equal sides or angles and lack symmetry. The video concludes with practice questions.

Explain what a right-angled triangle is and identify its longest side.

What are the characteristics of a scalene triangle?
