Question

PQ=PR=10cm andAQ=BR
CQ=1cm QM = 3 cm
find the perimeter of triangle PQR​

Answer 1

Answer:

Step-by-step explanation: Since PQ is 10 and PR is also 10,

QR=?

Therefore,

CR = 10 + 1 [Remaining side of triangle]

CR = 11.

QR = CR - CQ

QR = 11 - 1

QR = 10

Therefore all sides are equal = 10

Therefore Triangle PQR IS A EQUILATERAL TRIANGLE

Perimeter of the triangle = Side A + Side B + Side C = 10 + 10 + 10 = 30

There Perimeter of the triangle PQR = 30 UNITS .
