Question

In a triangle ABC , AB = 14cm , BC =48cm and AC = 50cm. Examine if triangle ABC is a right triangle. If yes which angle is equal to 90°?

Answer 1

Yes it forms a right angled triangle...
Ac^2=AB^2+AB^2
THATS.....2500=196+2304

AND ANGLE B IS 90°

Answer 2

in a right angled triangle the largest side is hypotenuse.
let triangle abc is a right angled triangle,
hypotenuse=50 cm.
base and perpendicular may be 14 cm and 48 cm.
by pythagorus theorem,

hypotenuse ^2=base ^2 +perpendicular ^2
(50cm) ^2= (48cm) ^2 + ( 14cm) ^2
2500 cm ^2 = 2,304cm ^2 + 196 cm ^2
2500 cm ^ 2=2500 cm ^2.

so triangle abc is a right angle right angled at vertex b.
