Question

4. Which of the following measurements can be the
sides of a right-angled triangle?
(a) 3 cm, 4 cm and 5 cm
(b) 23 cm, 24 cm and 25 cm
(c) 18 cm, 24 cm and 30 cm
(d) 16 cm, 30 cm and 32 cm​

Answer 1

Answer:

maybe be c but I m not sure

Answer 2

Step-by-step explanation:

(a)

a² + b² = c²

3² + 4² = 5²

9 + 16 = 25

25 = 25

Hence, it is right angled triangle.

(b)

a² + b² = c²

23² + 24² = 25²

529 + 576 = 625

1105 = 625

Hence, it is not right angled triangle.

(c)

a² + b² = c²

18² + 24² = 30²

324 + 576 = 900

900 = 900

Hence, it is a right angled triangle.

(d)

a² + b² = c²

16² + 30² = 32²

256 + 900 = 1024

1156 = 1024

Hence, it is not a right angled triangle.
