Math Problem Statement

Complete the proof that \( \overline{VX} \cong \overline{VW} \) using the given statements and reasons from the IXL Geometry problem involving isosceles triangles.

Solution

Let's work through the problem. Based on the image, you are tasked with completing the proof that VXVW\overline{VX} \cong \overline{VW} using the statements and reasons provided.

Steps for Completing the Proof:

  1. Statement: VYWX\overline{VY} \perp \overline{WX}
    Reason: Given. (The diagram shows VY\overline{VY} is perpendicular to WX\overline{WX}.)

  2. Statement: LWLX\angle LW \cong \angle LX
    Reason: Isosceles triangles have congruent base angles. (LWX\triangle LWX is isosceles.)

  3. Statement: LYWLYX\angle LYW \cong \angle LYX
    Reason: Corresponding angles of congruent triangles are equal. (LYWLYX\triangle LYW \cong \triangle LYX by the Angle-Angle Similarity postulate.)

  4. Statement: VYVY\overline{VY} \cong \overline{VY}
    Reason: Reflexive property of congruence. (Any segment is congruent to itself.)

  5. Statement: LWYLXY\triangle LWY \cong \triangle LXY
    Reason: ASA (Angle-Side-Angle) Congruence Postulate. (Two angles and the included side are congruent.)

  6. Statement: VXVW\overline{VX} \cong \overline{VW}
    Reason: Corresponding parts of congruent triangles (CPCTC).


Would you like me to clarify any of these steps in more detail?
