This is a right angled isosceles triangle because it has 1 right angle and 2 equal sides marked with a dash. We can use these properties to solve problems and find missing angles.Īn equilateral triangle has three equal sized side lengths and two equal sized angles.Įquilateral triangles have 3 equal sides and 3 equal angles. We can recognise right angled isosceles triangles because they have 1 right angle, 2 equal sides and 2 equal angles. We can recognise right angled triangles because they have one right angle. We can recognise scalene triangles because all the sides are different and all the angles are different. The 2 equal angles are the base angles of the isosceles triangle. We can recognise isosceles triangles because they have 2 equal sides and 2 equal angles. Equal sides are often labelled with dashes. We can recognise equilateral triangles because they have 3 equal sides and 3 equal angles. We also need to recognise that there are lots of different types of triangles and they are all unique because of the collection of properties each shape may have. We know that all triangles have 3 sides and 3 angles. This worksheet is a great resource for the 5th, 6th Grade, 7th Grade, and 8th Grade.We need to know the types of triangles and their properties.
