Question

Prove that UZ = YZ

hintHint:

Use the appropriate congruence rule.

The correct answer is: Hence proved


    Complete step by step solution:
    Consider 2 triangles, △XYZ and △WUZ
    From the figure, we have
    XZ = WZ (given)
    ∠XZY = ∠WZU (given)
    ∠XYZ = ∠WUZ (given)
    By angle sum property,
    Now, ∠YXZ = 180° - (∠XZY + ∠XYZ)
    ∠UWZ = 180° - (∠WZU + ∠WUZ) = 180° - (∠XZY + ∠XYZ)
    ⇒ ∠YXZ = ∠UWZ
    So, In △ XYZ and △WUZ
    ∠YXZ = ∠UWZ (proved)
    XZ = WZ (given)
    ∠XZY = ∠WZU (given)
    So, △XYZ ⩭ △WUV by ASA congruence criterion
    ⇒ UZ = YZ(corresponding parts of congruent triangles)
    Hence proved
