Answer 1

@saifoo.khan can you help me on this

Answer 2

im sure @dpaInc can solve..

Answer 3

i hope cause i really dont understand

Answer 4

hi saif..

Answer 5

Hey Dpalnc. sup?
can you solve this?

Answer 6

lol... picture is not loading...

Answer 7

ok got it.

Answer 8

an orthocenter is the concurrency of all the medians of a triangle... do you know what a median is?

Answer 9

yea i know what it is

Answer 10

then you can answer the question... it's one of the choices...

Answer 11

Dpanic's the boss at this.

Answer 12

Answer 16

hey... i just noticed is that where saifoo came from ? sifu?

Answer 17

PN = NQ
--------
because segment RN is a median

Answer 18

wow you guy's and that's the answer

Answer 19

Haha, NO how can i be a master when i never studied this "orthocenter" thingy? D:

And nope.. Saifoo's a nick. my real name is Saif (arabic name meaning sword).

Answer 20

lol... sifu Saifoo :)

Answer 21

I will try to study this topic from Dr. khan's site. ;)

Sifu. lol.

Answer 22

The point of concurrency of the medians is the centroid. The centroid O lies on segment RN. Therefore, segment RN is a median. Therefore, segmetn RN bisects the side to which it is drawn. Therefore, PN = NQ.

Answer 23

wow thank you, i think thats alot more understanding :)

Answer 24

Glad to help.
