Question

for finding AB and BC with the help of information given in the figure complete the following activity ​

Answer 1

Answer:

AB=BC=2

Step-by-step explanation:

AS GIVEN AB=AC

BY PYTHAGORAS THEOREM :

AB²+BC²=AC²

2AB²=√8²

AB²=8/2

AB=√4

AB=BC=2

Answer 2

AB = BC = 2 cm

Step-by-step explanation:

here , ABC is a right angled triangle

given

AB = BC

and AC = √8

therefore , using pythagoras theorem

AC² = AB² + BC²

(√8)² = AB² +AB²

(√8)² =  2AB²

8 = 2AB²

AB²= $\frac{8}{2}$

AB² = 4

AB = √4

AB = 2 cm

therefore , AB = BC = 2 cm

hence , AB = BC = 2 cm
