Question

See attached.
Here are the questions
a) Prove AKB= 90 (K=90)
b) Hence prove K is the mid point of DC

Answer 1

something is missing i think

Answer 2

wht is missing , its a parellollagrm

Answer 3

K does not need to be in the mid point, it could be anywhere

Answer 4

ok prove DK=KC or atleast prove K=90

Answer 5

that's the same of proving k is mid point of DC

Answer 6

so prove it..

Answer 7

like i said: k can be anywhere

Answer 8

not mid anymore

Answer 9

ok but it is in the midpoint in my diagram and prove it its n the midpoint of DC

Answer 10

its a question and u have to prove it..

Answer 11

but if you say it is mid point, so you are asuming it. It means there is nothing to prove...

Answer 12

the question says "prove that K is the midpoint of DC" so u hve to use the mathematics to prove that..

Answer 13

or you mean: by asuming <K =90º prove that K is mid point of DC.

Answer 14

yeah if so prove it?

Answer 15

kindly i am not getting your equation to prove. please clearify it. or i am having problem in distinguidh between equal sign and minus sign.

Answer 16

theres no minus sign its jst "equal"

Answer 17

ok. i try to prove it. it is old geometry. may i could succeeded.
you must have to w8 until itry.

Answer 18

check if i am right
