Answer:
Given : In Δ PQR
PQ =10cm QR =12cm PR =8cm
then we have to find the largest and smallest angle.
As the length of side are in the same order as the measure of the angles opposite the length of sides. The greatest side is opposite to the greatest angel .
By using the properties of triangle, if one angle of a triangle is larger than the other angel, than the side opposite to the larger angle is greater than the the side opposite to the smaller angle.
Longest side = QR = 12 cm
Therefore Greatest angel measure is P
Smallest side =PR = 8cm
Therefore smallest angle measure is Q
