Yamini,
1) In case of co-ordinate plane if we know slope-intercept equation of line y=mx+
b then how to find whether it goes through center (0,0)
Ans: if the intercept "
b" is equal to zero then the line passes through origin else not.
2) what is the equation for polygon external angles sum? For internal angles (n-2)180. (n is no.of sides).
Ans: For any polygon the sum of external angles is always equal to 360
3) In case of the traingles or polygons if they say as "measure of the sides" - does it mean length of the side or angle of the side.
Ans: I am not sure about this but I would have gone with the lenght of the side.
I hope it helps
Thanks
