Revision Questions 3-Feb-2008

Q1 : If the two vertices of a triangle are (3,-1) and (-2,3) and its orthocentre is the origin, find the coordinates of the third vertex.

Q2 : Find the length of perpendicular drawn from (2,-1) on the line 3x+4y=12.

Q3 : Deduce the length of the perpendicular for the point (x1,y1) on the line ax+by+c=0. Given that (0,-c/b) is on Y-axis while (-c/a,0) is on x-axis. (Hint : using area of triangle to obtain the result).

Prizes : The person who can get the answers correctly  in the fastest of time will win a variety of red packets.
