Question

lf angle pqr is an isosceles triangle such that pq=pr then prove that the altitude ps on qr bisects qr.please help me​

Answer 1

Answer:

Step-by-step explanation:

given ; PQ = PR

WKT in an isosceles triangle angles oppo. to equal sides are equal

so, ∠PQR=∠PRQ

InΔPQS & ΔPRS

PQ=PR

∠PQS=∠PRS

PS is common

ΔPQS≅ΔPRS

by CPCT

we have, QS=SR

hence proved
