(ii) 2 cm, 2cm
2 cm, 5 cm.
(iii) 1.5 cm, 2cm, 2.5 cm.
please Sahi answer dena​

Answer 1

Step-by-step explanation:

1.

1st side = 2.5 cm

2nd side = 6 cm

3rd side = 6.5 cm

2² + 6² = 4 + 36 = 40

6.5² = 42.25

therefore , 2²+6² ≠ 6.5²

hence 1. cannot be right angled ladder from the wall

2.

1st side = 2 cm

2nd side = 2 cm

3rd side = 5 cm

2² + 2² = 4 + 4 = 8

5² = 25

therefore, 2² + 2² ≠ 5²

hence 2. also cannot be right angled ladder from the wall

3.

1st side = 1.5 cm

2nd side = 2 cm

3rd side = 2.5 cm

1.5² + 2² = 2.25 + 4 = 6.25 cm

2.5² = 6.25 cm

Therefore, 1.5² + 2² = 2.5²

hence 3. is right angled ladder from the wall
