Chapter 10, Lesson 3
Connie conjectured that tangent segments to a circle from an external point are congruent. To verify her conjecture, she created congruent triangles by drawing radii perpendicular to the tangents. So Connie's conjecture is actually a fact.
Use Connie's fact to help you solve this problem.
In this figure, a circle is inscribed in quadrilateral MATH. What is the perimeter of MATH?
