Answer 2

Answer:

Hope this helps you!! Mrk as Brainlist

Step-by-step explanation:

Given

PQ=19cm

QR=24cm

PR=30cm

Prove=ΔPQR is not right angled Δ

to prove this we will use the Pythagoras theorem

PR²=PQ²+QR²

30²=19²+24²

900=361+576

900≠937

LHS≠RHS

Therefore it doesnt satisfy the Theorem Hence its not a right angled Triangle.
