The measure of an exterior angle of a triangle is equal to the sum of the measures of its two remote interior angles.
Two sides and the included angle are equal.
Master Plane Euclidean Geometry: Theory, Core Concepts, and Problem-Solving Resources
Apply Thales' Basic Proportionality Theorem, which states parallel lines cut triangles into proportional segments. Set up the geometric ratio: Substitute the given values: Simplify the fraction: Solve for the missing segment: Level 3: Advanced Theoretical Challenges
If a straight line falling on two straight lines makes the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which the angles are less than the two right angles. Fundamental Elements
