If all three angles are exactly the same measure, how big is each angle?
Hint:    x + x + x  = 180

• 180 degrees

• 90 degrees

A triangle has angles measuring (64 degrees, 25 degrees, and 88 degrees). What would this triangle be classified based on its angles?

• Equilaterlal Triangle

• Right Triangle

• Acute Triangle

Find Angle 1, Angle 2, and Angle 3. 

• Angle 1 = 45, Angle 2 = 45, Angle 3 = 135

• Angle 1 = 135, Angle 2 = 55, Angle 3 = 55

• Angle 1 = 55, Angle 2 = 55, Angle 3 = 125

• Angle 1 = 40, Angle 2 = 40, Angle 3 = 135
