In this type of triangle one of its angles measures more than 90 degrees. In this case we can assume that a = 30 and b = 40 . If we know the shorter leg length a, we can find out that: b = a3 c = 2a If the longer leg length b is the one parameter given, then: a = b3/3 c = 2b3/3 Area of triangle is also possible to calculate different ways with angles and lengths of the triangle. Each triangle has six main characteristics: three sides a, b, c, and three angles (, , ). Tick marks on the edge of a triangle are a common notation that reflects the length of the side, where the same number of ticks means equal length. Their angles are also typically referred to using the capitalized letter corresponding to the side length: angle A for side a, angle B for side b, and angle C (for a right triangle this will be 90) for side c, as shown below.
