Question
Choose the correct equation for finding c .
- 52 + b2 = c2
- 52 + 122 = c2
- 122 + c2 = 52
- C = 12 -5
Hint:
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Using this theorem we can find the required equation.
The correct answer is: 52 + 122 = c2
Using Pythagoras theorem,
perpendicular, p= 5, base, b = 12, hypotenuse, h = c
