In triangle ABC, the altitude from B is tangent to the circumcircle of ABC. Prove that
the largest angle of the triangle is between 90◦ and 135◦. If the altitudes from both B and
from C are tangent to the circumcircle, then what are the angles of the triangle?
Well its obvious that it must be greater than 90 degrees due to cyclic quads.
The Attempt at a Solution
Ive attempted and physically shown its impossible to have one greater than 135 degrees, and ive actually proven the 90 degrees. How do i prove the 135 degree cap? And how do i do the other part?
