Answer 1

@superdavesuper Help me here

Answer 2

See the two small triangles on the left n right of line segment l? if u can prove them congruent, then R will be equidistant from pt C n D. follow me so far?

Answer 3

yes i am following u

Answer 4

go ahead

Answer 5

i think they are congruent because I intersects mid of CD

Answer 6

:) hahahaha u hardly need me :P

Answer 7

i will give u 1 more hint: l is not just the bisector of CD....it is the perpendicular bisector....

Answer 8

i still didnt get nd sory i was having a coffee so that i dont sleep

Answer 9

i really need your help

Answer 10

OK Im back :)

Answer 11

Where did u get stuck? u were doing just fine before

Answer 12

wen u said .it is the perpendicular bisector

Answer 13

well back to wat u said be4, can u provide the two triangles are congruent?

Answer 14

i mean prove...sorry

Answer 15

yes because the line that R is intersected is the mid point of CD
am i correct

Answer 16

yes so u got 1 side...what else do u have to prove congruent?

Answer 17

i mean the line goes all the way to R from the midpoint of CD

Answer 18

yup yup

Answer 19

then whats next

Answer 20

what other info u know about the two triangles? any more info about their sides?

Answer 21

or angles? look at the picture n see what the two triangles have in common :)

Answer 22

side CR EQUAL TO SIDE DR AND ANGLE C EQUALS TO ANGLE D

Answer 23

no, u dont know CR=DR that is the thing u are trying to prove here. same for angle C n D....

Answer 24

but what about the third side of these two triangles?

Answer 25

dont know

Answer 26

Need more coffee? :P Look again at two triangles - u got 1 of the 3 sides being equal because l is the bisector. CR n DR u dont know. how about the third side??

Answer 27

Angle R u mean

Answer 28

or u mean CD

Answer 29

Nope there are 3 sides for a triangle.....

Answer 30

yes CR DR nd CD

Answer 31

right

Answer 32

Not the big triangle but the two smaller triangles; one on the left n one on the right

Answer 33

CR CI RI the one on the left

Answer 34

I is 90°

Answer 35

There u go - so now u have one side and one angle of the two triangle being the same right?

Answer 36

yes

Answer 37

So all u need is one more side then u can prove the two triangles congruent right?

Answer 38

yes

Answer 39

But wait - look at the picture....aren't both triangle sharing one side? :P

Answer 40

they are sharing RI

Answer 41

Woooohooooo so are the two small triangles congruent?

Answer 42

yes and now lets conclude all the answer in one sentence

Answer 43

u do it :P im sleepy here zzzzzz

Answer 44

lol oright good night nd thnxs

Answer 45

Have a peacefull sleeep
