Which of the following are the sides of a right-angled triangle?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 12 cm, 16 cm, 20 cm.
In a right-angle triangle, Hypotenuse2 = Base2 + Perpendicular2
From the options, it can be seen that
Hypotenuse = 20
Base = 12
Perpendicular = 16
⇒ 122 + 162 = 202
⇒ 144 + 256 = 400
⇒ 400 = 400
Hence, option 3.
