Question

if d and e are the points on sides ab respectively such that abc is isosceles triangle​

Answer 1

Answer:

PLEASE DON'T GIVE NON SENSE ANSWER..

Step-by-step explanation:

GIVEN : In Δ ABC, DE || BC and BD = CE.

To prove : Δ ABC is isosceles.

AD / BD = AE/EC

[By using basic proportionality theorem]

AD = AE

[ BD = CE ]

So, AD + BD = AE + CE.

[BD = CE & AD = AE]

Therefore, AB = AC.

~Hence, Δ ABC is isosceles.

Answer 2

Step-by-step explanation:

GIVEN : In Δ ABC, DE || BC and BD = CE.

To prove : Δ ABC is isosceles.

AD / BD = AE/EC

[By using basic proportionality theorem]

AD = AE

[ BD = CE ]

i

So, AD + BD = AE + CE.

[BD = CE & AD = AE]

Therefore, AB = AC.

~Hence, Δ ABC is isosceles.
