• Any Triangle
All angles add up to 180o
Special triangles:• Isosceles Triangle: 2 equal angles
• Equilateral Triangle: 3 equal angles (all 60o)
Only need 1 angle
to find all the rest
All angles equal, s
o
all angles 60o

Total angles in 3 triangles = 3 x 180 = 540o
What is the smallest number of triangles you can split this shape up into?
So total angles in a pentagon = 540o

4 triangles = 4 x 180 = 720o
Hexagon = 6 sides

5 triangles = 5 x 180 = 900o
Heptagon = 7 sides

10 triangles = 10 x 180 = 1800o
Dodecagon = 12 sides
