Question

In AABC, ifAB2= AC2+ CB?, state with reason whether AABC
is a right angle triangle or not​

Answer 1

Answer:

In △ABC,

⇒ (AC)

2

=(BC)

2

+(AB)

2

[ Given ] --- ( 1 )

Pythagoras theorem,

⇒ (Hypotenuse)

2

=(oneside)

2

+(otherside)

2

---- ( 2 )

Comparing ( 1 ) and ( 2 ) we get, AC is a hypotenuse of a triangle.

⇒ Hypotenuse is the longest side of a right-angled triangle, opposite the right angle.

⇒ Opposite angle of AC is ∠B.

∴ ∠B is a right angle of △ABC.

Answer 2

Answer:

CB²

Step-by-step explanation:

Because in a right angled triangle the sum of the squares of the 2 sides is equal to the square of the hypotenuse of the right triangle.
