@FriedRice

@i0iz0gangster can you help?
OpenStudy (vishweshshrimali5):
What do you think should be the answer ?

I think C
OpenStudy (vishweshshrimali5):
WHy ?
OpenStudy (anonymous):
But im not the best as this ;/
OpenStudy (vishweshshrimali5):
The option B is actually not clear. Can you tell me what's in the option ?
OpenStudy (anonymous):
look at the angle markings

Ah, i have no idea :/ I was looking at A also cause the symbols are in the same area
OpenStudy (vishweshshrimali5):
Actually, B is not correct.
As, @FriedRice , with the help of angle marking , you can say that which angles are equal
OpenStudy (vishweshshrimali5):
See: in first triangle angle C has 2 lines marked on it and similarly, in second triangle, angle R has 2 lines marked on it.
So, <C = <R
OpenStudy (vishweshshrimali5):
Can you tell me which other pair of angles is equal ?
OpenStudy (anonymous):
B & P? @vishweshshrimali5

Yay! :)
OpenStudy (vishweshshrimali5):
No no see that angle B has 1 line and angle P has no line .
OpenStudy (anonymous):
ohhhh
OpenStudy (vishweshshrimali5):
Its okay
OpenStudy (anonymous):
ah I suck at this :/

Its no problem.
OpenStudy (vishweshshrimali5):
Now, tell me what is the sum of all angles of a triangle ?
OpenStudy (anonymous):
90?
OpenStudy (vishweshshrimali5):
No its 180
OpenStudy (anonymous):
that was my second choice lol

:D
Okay, now I am not going to prove this but remember that when two angles of 2 triangles are equal then the third angle will also be equal.
OpenStudy (vishweshshrimali5):
Thus, <A = <P
OpenStudy (anonymous):
Ohhhh
OpenStudy (anonymous):
So C?
