Solution:
QUESTION: 5

ΔABC is right-angled at C. If AC = 5 cm and BC = 12 cm find the length of AB.

Solution:

We can find out the value of AB by using Pythagoras theorum,

that is AB²=BC²+AC²

AB²=12²+5²

AB²=144+25

AB²=169

AB=√169

AB=13cm

QUESTION: 6

ΔPQR is a triangle right-angled at P. If PQ = 3 cm and PR = 4 cm, find QR.

Solution:
QUESTION: 7

Which is the longest side in the triangle PQR right angled at P?

Solution:

The side opposite to greater angle is greater, and in a right angled triangle, the right angle is the largest angle. So side opposite to it is the largest and known as hypotenuse. In our question, since right angle is at P so the side opposite to it will be QR.
