Question

The triangle ABC formed by AB = 13cm, BC = 5cm, and AC = 12cm is

Answer 1

Answer:

right angles triangle

Step-by-step explanation:

(5)^2 + (12)^2 = (13)^2

Answer 2

Answer:

∵ s= (13 + 5 + 12) / 2 cm

= 15cm

s-a = 2 cm,

s-b = 10 cm and

s-c = 3 cm

⇒ Area = √ (15 x 2 x 10 x 3 ) cm2

= 30 cm2

⇒ (12 x h) / 2 = 30

∴ h = 5 cm
