Triangles All Around

Can you find all the different triangles on these peg boards, and find their angles?

Finding all the angles in these triangles is rather tricky, but well done to those of you who tried. Some of you measured the ones you couldn't work out using a protractor.

Georegie from St Lucifiers correctly identified the triangles and gave some of the angles, although you didn't say how you calculated them, Georegie:


A = Equilateral ($60$ $^\circ$, $60$ $^\circ$, $60$ $^\circ$)

B = Isosceles ($30$ $^\circ$, $30$ $^\circ$, $120$ $^\circ$)

C = Right angle scalene ($90$ $^\circ$, $30$ $^\circ$, $60$ $^\circ$)

E = Scalene

Ryo and Jake from Moorfield Junior told us that D is an isosceles triangle, but didn't give the angles - well done to you both. The angles in D were very tricky to calculate.
