All triangles have 3 sides and 3 angles. The sum of the triangles angles is 180 degrees. Isosceles triangles are triangles with two sides of equal length and two angles of equal degree. Equilateral triangles are triangles with three sides of equal length and three angles of equal degree. Fill in the missing angles. 2. Fill in the missing angles.
