Playing with triangles to become familiar with their properties 3 Mar 2013

This week we have been learning about the names and properties of different triangles in maths. We know an equilateral triangles has: 3 sides measuring the same length, three angles of 60 degrees and three lines of symmetry. An Isosceles has 2 sides the same length and two angles the same size and one line of symmetry. A scalene has none of these properties as the size of all sides and lengths are different and it has no lines of symmetry. Do you know all these facts?
