• # question_answer1) Use the figure to name (a) five points (b) a line (c) four rays (d) five line segments.

From the given figure, (a) Five points are B, C, D, E and O. (b) A line is $\overset{\leftrightarrow }{\mathop{BD}}\,$(or$\overset{\leftrightarrow }{\mathop{OB}}\,$). (c) Four rays are $\overset{\to }{\mathop{OB,}}\,\overset{\to }{\mathop{OC,}}\,\overset{\to }{\mathop{OE,}}\,$ and $\overset{\to }{\mathop{OD.}}\,$ (d) Five line segments in the given figure are $\overline{OB},\overline{OC},\overline{OE},\overline{OD}$ and $\overline{DE}.$ Note Two points are enough to fix a line. Hence, we can say that two points determine a line.
