Question

Can we do this question by this method? This is question number 9 , excerise 10.2 (NCERT).

I am confused because this is a very short solution

Will mark the appropriate answer as branliest​

Answer 1

❥A᭄ɴsᴡᴇʀ࿐:

THIS METHOD IS WRONG.

THE correct method is

Consider the following diagram.

Here, it is given that AOB = COD i.e. they are equal angles.

Now, we will have to prove that the line segments AB and CD are equal i.e

AB=CD

Proof:

Proof:In triangles AOB and COD,

Proof:In triangles AOB and COD,AOB = COD

(as given in the question)

(as given in the question)OA = OC and OB = OD

(these are the radii of the circle)

(these are the radii of the circle)So, by SAS congruency, ΔAOB ΔCOD.

(these are the radii of the circle)So, by SAS congruency, ΔAOB ΔCOD.∴ By the rule of CPCT, we have

(these are the radii of the circle)So, by SAS congruency, ΔAOB ΔCOD.∴ By the rule of CPCT, we haveAB = CD. (Hence proved).
