Question

In Δ ABC, if AB2 = AC2 – BC2 , state giving reason whether ΔABC is a right angled triangle or not.​

Answer 1

Answer:

According to Pythagoras theorem ∆ABC is a right angled triangle.

Step-by-step explanation:

In a right angled triangle, ∆ABC;

where AB and BC are two adjacent sides; ( perpendicular and base)

and AC is the hypotenuse.

According to Pythagoras theorem, we have;

AB^2+BC^2=AC^2

=> AB^2= AC^2-BC^2

SO WE CAN SEE THAT THIS EQUATION PROVES THAT ∆ABC IS A RIGHT ANGLED TRIANGLE.
