Answer 1

ANSWER:-

Given:

In the given figure, if AB= AC & DB= DC.

To find:

Find the ratio of ∠ABD to ∠ACD.

Solution:

Assume the figure,

Here,

⏺️AB= AC

⏺️DB= DC

Now,

In ∆ABC & ∆DBC are Isosceles∆.

Since,

AB = AC

&

DB= DC

Therefore,

∠ABC = ∠ACB &

∠DBC = ∠DCB [angle opposite equal sides]

So,

Let ∠ABD :∠ACD

(∠ABC - ∠DCB) : (∠ACB - ∠DCB)

(∠ABC -∠DBC): (∠ABC - ∠DBC)

[since, ∠ABC=∠ACB & ∠DBC=∠DCB]

=) 1:1

Therefore,

∠ABD: ∠ACD = 1:1.
