Complete the following proof. Given: AB, CD are diameters. Prove: BD=CA

Step-by-step explanation:

1. if AB& CD are diameters, then AB=CD, and then OA=OB=OC=OD - radiuses.

It means, OA=OB and OC=OD.

2. m∠(AOC)=m∠(BOD);

3. according to the 1. & 2 ΔAOC=ΔBOD, then BD=CA

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
