Question

In triangle PQR, P=70 and R=30. Which is the longest side. Give reason

Answer 1

Let's Say, ANGLE Q = 90°
Now, PQ=70 units
And, RQ=30 Units

So, Using P/T
PR^2=PQ^2 + RQ^2
PR =490 + 900
PR =√1390
Take out the square root

So we can see that the hypotenuse is the longest side of the triangle PQR
