Use the figure to name: Four rays.

Given figure is, A ray is a portion of a line. It starts at one point (called starting point or initial point) and goes endlessly in a direction. From the figure, We can see that the ray start from point O . Hence, Four rays are: O D → , O E → , O C → , O B → .

Use the figure to name: Five-line segments.

Given figure is: A line segment is part of line that is bounded by two end points. From the figure, Five-line segments are: DE , OE , OC , OB , OD .

Use the figure to name: Line containing point E .

Given figure is, We know that, Infinite lines can passes through a point. A line is a set of points that continues infinitely in both the directions. From the figure we can see that, the lines containing E are: AE ↔ , BE ↔ , DE ↔ and FE ↔

Use the figure to name: Line passing through A .

Given figure is, We know that, Infinite lines can passes through a point. A line is a set of points that continues infinitely in both the directions. Now, In given figure, Lines passing through A : A E ↔ , B A ↔ and D A ↔

Use the figure to name: Line on which O lies

A line is a set of points that continues infinitely in both the directions. We need minimum two points to represent a line. A line on which O lies : CO ↔ or OC ↔ and B O ↔ or O B ↔

Use the figure to name: Two pairs of intersecting lines.

Given figure is, Lines that intersect at a single point is known as intersecting lines. In figure, Two pairs of intersecting lines are: AD ↔ and OC ↔ (Since which are intersecting at . B ) AE ↔ and FE ↔ (Since which are intersecting at . E )
