Question

if triangle ABC congurent to Triangle PQR, AB=5, BC = 7, AC =9, PQ=10 then find QR&PR​

Answer 1

Answer:

QR = 14

PR = 18

maybe these answers are correct

Answer 2

In ∆ ABC

AB = 5

BC = 7

AC = 9

In ∆ PQR

PQ= 10

We will find the value using CPCT

BC=QR=7

PR=AC=9

_________________________

CPCT Concept :-

(Corresponding Parts of Congruent Triangles are Congruent)

This concept is generally used to prove equal angles or sides of the two triangle .

We can prove equal by congruent method .

__________________________

Criterion of CPCT Concept :-

SSS - All the 3 sides are equal

AAS - 2 angles are equal

SAS - 2 sides are equal

ASA - 2 Angles are same

RHS- There should be 90°
