I don't know what complete sentences are :P

but, derive it using sum of areas of two adjacent triangle pairs. (like ADC and ABC or DAB and DCB)

anonymous · Answer

ah, ty, and complete sentences means just to restate the question.

apoorvk · Answer

I know that lol, but am not doing that for you.

Do you get any idea how we can find the area of those triangles?

anonymous · Answer

no, not inless there are actual measurements for the triangles.

apoorvk · Answer

lol, i mean in terms of the variables?

anonymous · Answer

well i guess no.. lol..

apoorvk · Answer

just assume the centre point as O.

then area of triangle ABC in terms of BO and AC?

apoorvk · Answer

do you know that area of a triangle is (1/2) * base * height?
here in triangle ABC, the BASE is AC, and BO is the HEIGHT.

Feel that way?
