4cm and blue was 5cm.These are all my triangles:
There are ten different triangles.
Ruth from Swanbourne House School gave us a little more detail about the triangles:
3 equilateral triangles where all sides are equal (3x3cm, 3x4cm and
1 right angled triangle, with 1x3cm, 1x4cm and 1x5cm rod.
The other 6 were isoceles triangles, where two of the sides were equal.
Thank you to both of you.
