## Homework Statement

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?

## Homework Equations

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?
