Question

6. The angles of triangle ABC measure 30 degrees, 40 degrees, and 110 degrees. Will

its circumcenter fall inside the triangle, on the triangle, or outside the
triangle? Explain your reasoning.

Answer 1

Answer: Outside the triangle

Explanation:

Because one of the angles has a measure greater than 90 degrees, we know that the triangle must be obtuse. Therefore, the circumcenter must fall outside the triangle because in an obtuse triangle, the circumcenter is always located outside of the triangle.
