Question

state weather ABC is traingle or no if P PQ=6cm,QR=7cm PR=29cm​

Answer 1

Step-by-step explanation:

We have

(

AC

AQ

)=

9

3

=

3

1

(

AB

AP

)=

10.5

3.5

=

3

1

In ΔAPQ & ΔABC

(

AC

AQ

)=(

AB

AP

)

& ∠PAQ=∠BAC

Thus ΔAPQ∼ΔABC by SAS criterion.

Hence (

AC

AQ

)=(

BC

PQ

) (by cpst)

⇒

3

1

=(

BC

4.5

)

⇒BC=13.5cm.
