Question

9 POR is
is an isosceles triangle
such that po- PR, then prove
that the altitude ps from P on QR
bise et OR.​

Answer 1

Answer:

so, altitude PS divides triangle POR into two triangles, PSO and PSR

so in triangles, PSO and PSR

PS =PS (common)

PO= PR (given)

angle O = angle R (isosceles triangle)

by ASA congurency criteria

triangle PSO _~_ triangle PSR

therefore, from above OP =OR

therefore OR is bisected
