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:

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.
