⚘Solution:------

Given:

  • In the isosceles XYZ, XY=XZ

To prove:

  • XYZ = XZY

Construction:

  • Draw a line XM such that it bisects ∠YXZ and meets the side YZ at M.

Proof:

ㅤㅤㅤㅤㅤㅤㅤIn △XYM and △XZM

ㅤㅤㅤㅤㅤㅤㅤㅤXY = XZ (Given)

ㅤㅤㅤㅤㅤㅤXM = XM (Common Sides)

ㅤㅤㅤ∠YXM = ∠ZXM (XM BISECTS YXZ)

△XYM ≅ △XZMㅤㅤㅤㅤㅤㅤㅤㅤㅤ[By SAS criterion]

∠XYZ = ∠XZY ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤC.P.C.T

ㅤㅤㅤㅤㅤ⚘Hence, Proved!!
