Besides, we will see how to calculate the area of a triangle, area of an equilateral triangle, area of an isosceles triangle and heron’s formula. Also check the solved examples.

Properties of symmetry: - Students may notice symmetry in the isosceles and equilateral triangles and non-symmetry in the scalene triangles Informal recognition of these properties may be helpful in ...

Discover the different types of triangles and find out the difference between an equilateral, scalene, isosceles and right-angled triangle in this KS2 guide.
