if a triangle abccongrent triangle pqr and ab =5cm bc3cm and ac2.5 cm what is the length of pr​

Answer 1

Answer:

$\sf \: The\: property \:is \:shown\: in \\ \tt \: a+b=b+a is the \\ \tt Commutative \:Property \\ \tt of Addition. \\ \tt 1) The commutative \:property \\ \tt of\: addition \:states\: that \:while \\ \tt adding\: any\: of \:the \:two \:numbers \\ \tt in\: any \:order\: that\: won't \:affect\: the \\ \tt \: final\: answer \:of \:the\: addition$

Answer 2

Step-by-step explanation:

Given, △ABC∼△PQR, as corresponding sides of similar triangles are proportional,

∴

PQ

AB

=

QR

BC

=

RP

CA

=

k

1

(let)

Also, AB=5,BC=6,AC=7 So, PQ=5k,QR=6k,RP=7k

Perimeter of △PQR=PQ+QR+RP

⇒360=5k+6k+7k⇒360=18k⇒k=20

Thus, PQ=5×20=100,QR=6×20=120,RP=7×20=140
