Solution

## COLLINEAR POINTS : Three or more points in a plane are said to be collinear if they all lie in the same line. This line is called the line of collinearity for the given points. (i) We can draw only one line passing through three collinear points. (ii) 3 Line segments are: $\overline{AB}\phantom{\rule{0ex}{0ex}}ThisisbecauseithastwoendpointsAandB.\phantom{\rule{0ex}{0ex}}\overline{BC}\phantom{\rule{0ex}{0ex}}ThisisbecauseithastwoendpointsBandC.\phantom{\rule{0ex}{0ex}}\overline{AC}\phantom{\rule{0ex}{0ex}}ThisisbecauseithastwoendpointsAandC.$
