This is how an equilateral triangle looks like: As you can see, this is an equilateral triangle with a side length of "a" units and a height of "h" units. Then if we call the side length a, the side across from 30 degrees will be a/2 units long. Triangle has three types based on its three angles, including obtuse (1 angle > 90 ̊C), right (1 angle = 90 ̊C) and acute (no angle > 90 ̊C).
