Question

In ∆PQR, PQ = 10 cm, QR = 12cm, PR = 8 cm, find the biggest and the
smallest angle of the triangle

Answer 1

Step-by-step explanation:

Given In triangle pqr. pq =10 cm qr= 12 pr=8 then we have to find the greatest and smallest angle.

As the length of side are in the same order  as the measure of the angles opposite the lengths of sides. The greatest side is  opposite to the greatest angle.

By using the rule

, if one angle of a triangle is larger than the other angle,  then the side opposite to the larger angle is greater than the side opposite to the smaller angle.

Longest side=qr=12

∴ Greatest angle measure is ∠p

Smallest side=pr=8

∴ Smallest angle measure is ∠q

this is your answer......
