6. Inequalities in Two Triangles
Sign In
Focus on the triangles △ WZX and △ YZX.
WX>XY
Let's highlight the segments we are asked to compare.
Now we will summarize what we know about triangles △ ZWX and △ ZYX.
| Claim | Justification |
|---|---|
| ZW≅ZY | Both of these segments have a measure of 6. |
| m∠ WZX> m∠ YZX | 55>45 |
Since ZX is a common side, triangles △ ZWX and △ ZYX have two pairs of congruent sides. This means that we can apply the Hinge Theorem. m∠ WZX> m∠ YZX ⇓ WX> XY
