Question

PQR is an isosceles triangle such that PQ=PR, then Prove that the altitude
PS from P on QR, bisect QR​

Answer 1

Answer:

PS divides triangle PQR into 2 triangles PSQ and PSR

in triangle PSQ and triangle PSR

PS =PR (given)

PS =PS (common altitude)

angle Q = angle R (isosceles triangle)

by SAS congurency criteria

triangle PSQ congurent to traingle PSR

from above, PQ =PR

this QR is bisected
