Question

pr is an altitude of an isosceles triangle pqr where PQ = pr. prove that p bisects QR.

Answer 1

$\huge\underline{\overline{\mid{\bold{\black{AnSwer -}}\mid}}}$

☞Given :-

• PQ= PR

☞to find :-

• p bisects QR

☞SoLution :-

ln ∆PQS & ∆PSR

→PQ = PR. [ given]

→PS = PS. [ common]

→ PSQ = PSR. [right angle]

by SAS criteria....

∆PQS ≈ ∆ PRS

QPS = RPS [ by cpct]

hence, angle p bisects QR
