WebExterior Angle Theorem. Statement: If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles. The above statement can be explained using the figure … Web2 de feb. de 2024 · An exterior angle of a triangle is equal to the sum of the opposite interior angles. Every triangle has six exterior angles (two at each vertex are equal in measure). The exterior angles, taken one at each vertex, always sum up to 360 ° 360\degree 360°. An exterior angle is supplementary to its adjacent triangle interior angle. WebStep 2: Use what we learned from Case A to establish two equations. In our new diagram, the diameter splits the circle into two halves. Each half has an inscribed angle with a ray on the diameter. This is the same situation as Case A, so we know that.
