WebJun 26, 2024 · b) alternate exterior angles theorem. Step-by-step explanation: When two lines are cut by a transversal, the alternate exterior angles are congruent. In the first diagram: x and y are congruent; a and b are congruent; Comparing with our given lines, j, k and m. We can see that the two given angles are in the same position as in the first image. 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. (1)\quad\purpleC {\theta_1}=2\blueD {\psi_1} (1) θ1 = 2ψ1. and. ishop avon indiana
