Question

In ΔPQR, ∠Q=90°, PQ=QR. Find ∠P​

Answer 1

꧁ᎪΝՏᏔᎬᎡ꧂

IN TRIANGLE PQR,

ANGLE Q = 90 DEGREES

ANGLE P AND R ARE EQUAL BCOZ THE TWO SIDES PQ AND QR ARE EQUAL

THEN.......

180 - 2 ANGLE P = 90

2 ANGLE P = 90

ANGLE P = 45 DEGREES......

Answer 2

Answer:

here angle Q=90

PQ=QR

From property of isosceles triangle

opposite angles are congruent due to congruent sides .

opp. angle of PQ=angle R

Opp.angle of QR=angle angle P

let angle P and R are x

angle P+Q+R=180........(property of traingle)

x+90+x=180

2x=180

x=90

Therefore,

angle P=90
