When none of the sides of a triangle have equal lengths, it is referred to as scalene, as depicted below. The center of this circle, where all the perpendicular bisectors of each side of the triangle meet, is the circumcenter of the triangle, and is the point from which the circumradius is measured. Likely the most commonly known equation for calculating the area of a triangle involves its base, b, and height, h. The "base" refers to any side of the triangle where the height is represented by the length of the line segment drawn from the vertex opposite the base, to a point on the base that forms a perpendicular. The most important rule is that this triangle has one right angle, and two other angles are equal to 45. In our case, one leg is a base, and the other is the height, as there is a right angle between them. If two angles are known and the third is desired, simply apply the sum of angles formula given above. So, c = 50.
