Question

in the right triangle <ABC <B=90° if ab =9cm bc =12 cm find the sum
​

Answer 1

Answer:

ABC

Step-by-step explanation:

AB = 9 cm

CB = 40 cm

AC = 41 cm

The given triangle will be a right angled triangle if square of its largest side is equal to the sum of the squares on the other two sides.

According to Pythagoras Theorem,

(AC)2 = (BC)2 + (AB)2

(41)2 = (40)2 + (9)2

1681 = 1600 + 81

1681 = 1681

Hence, it is a right-angled triangle ABC.

hope it works....!
