Answer 1

I just don't know this? It's not like there is a theorem stating all chords are equal.

Answer 2

careful, intersecting chords theorem says this :-

\(\text{product of segments of one chord, equals product of segments of second chord}\)

Answer 3

you just need to multiply, instead of adding.

Answer 4

according to intersecting chords theorem :-

PA x PD = PC x PB

Answer 5

Ooh intersecting chords? Didn't know about that theorem..:)

Answer 6

:) hre is a simple visual explanation

Answer 7

Question, there was a dispute about the answer to this:

Answer 8

you've picked the correct option !

wat dispute ?

Answer 9

It was on a post of mine, people were just disagreeing haha.
And this one? I think it is either C or D.

Answer 10

I said C, but someone that was helping me said D then got off, so I just took their word :-P

Answer 11

D is correct !
after proving triangles, OSD & OTB are congruent, we use CPCTC and conclude OS = OT

Answer 12

how did u pick C, there is not a single ASA triangle i see in that diagram...

Answer 13

What makes OSD & OTB congruent?

Answer 14

lets prove this :)

here is the theorem we want to prove :-
Prove that congruent chords in a circle are equidistant from center

Answer 15

Are the triangles similar by AAS?
Also, another question.

Answer 16

1) CD = AB 1) Given
2) OD = OB 2) radii of same circle
3) DS = BT 3) perp from center bisects the chord
4) \(\triangle OSD \cong \triangle OTB \) 3) By LH congruence theorem
5) OS = OT 5) Corresponding parts of congruent triangles are congreunt

Answer 17

thats for previous question okay

Answer 18

the pic and ur question are not relating,
you asked Are the triangle similar by AAS,
but in the pic i see squares and oly 1 triangle ??? check once :)

Answer 19

I was referring to the other question :P But I see how you get it now.

Answer 20

ohk i get u :)

Answer 21

pic shows a classic proof of Pythagorean theorem

Answer 22

It's D, right?
