A right triangle is formed by connecting the 3 coordinates A, B and C as shown in the figure. Find the point B if AB and BC are parallel to the coordinate axes.
(1, 1)
The point B lies on both the lines AB and BC. Hence, it passes through both the lines AB and BC.
Since BC is parallel to X-axis, the ordinate of point B is 1.
AB is parallel to Y-axis, so its abscissa is 1.
The point B is (1,1).
