Question

4) In A PQR, PQ=10cm, QR=12cm
PR=8cm Find out the greatest
angle of the triangle.​

Answer 1

Answer:

• draw a line of 10 cm is PQ.

• then draw QR =12 cm .

Both sides.

Answer 2

Answer:

Step-by-step explanation:

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....
