Types of triangles at a glance


There are four different types of triangles that we need to know about. Equilateral triangles have 3 equal side lengths and 3 equal angles, isosceles triangles have 2 equal sides and 2 equal angles whilst scalene triangles have sides and angles which are all different. Right angle triangles, sometimes called right triangles, are triangles which contain a right angle. Right angle triangles can be isosceles or scalene. 


Triangles can contain acute angles, obtuse angles or right angles. Since the angles of a triangle add up to 180°, a triangle can contain at most one right angle or obtuse angle. A triangle with an obtuse angle is called an obtuse triangle and a triangle where all three angles are acute is called an acute triangle.


Looking forward, students can then progress to additional polygons worksheets and other geometry worksheets, for example a simplifying expressions worksheet or simultaneous equations worksheet.
