6. Inequalities in Two Triangles
Sign In
Identify congruent sides in the triangles.
ST>QT
Let's copy the diagram and highlight the segments we are asked to compare.
We can see that two sides of △ SRT are congruent to two sides of △ QRT. However, the included angle in △ SRT is larger than the included angle in △ QRT. QR≅RS RT≅RT m∠ SRT> m∠ QRT Therefore, by the Hinge Theorem, the third side of △ SRT is longer than the third side of △ QRT. ST> QT
