In the figure, seg AB | Y-axis and
seg CB X-axis. Co-ordinates of
points A and C are given.
To find AC, fill in the boxes given below
A ABC is a right angled triangle.
According to Pythagoras theorem,
(AB) + (BC)=0
We will find co-ordinates of point B
to find the lengths AB and BC,
CB || X-axis y co-ordinate of B =
BA || Y-axis .. co-ordinate of B=0
AB=-=
BC =
AC = C+=0
