Given " A B ¯ ‖ C D ¯ , l ⊥ m " . Which are perpendicular? Which are parallel?

The lines that never meet even if they are extended any further are called Parallel lines. It is denoted by symbol " ∥ " . If line P is parallel to line Q , we denote this by writing P ∥ Q . We read this as P is parallel to Q . The lines that meet each other with 90 ° as angle between are called perpendicular lines. It is denoted by " ⊥ " . If line P is perpendicular to line Q , we denote this by writing P ⊥ Q . We read this as P is perpendicular to Q . Given " A B ¯ ‖ C D ¯ , l ⊥ m " Hence, the line segment A B ¯ is parallel to the line segment C D ¯ and the line l is perpendicular to m .

Match the following 1 . Set square A ) to measure angles 2 . Protractor B ) to measure the length of the line segments 3 . Divider C ) to draw parallel lines

Set squares are useful for drawing parallel lines and perpendicular lines. A protractor is a measuring instrument for measuring angles. Divider is an instrument for measuring,or marking off distances. So 1 . Set square C ) to draw parallel lines 2 . Protractor A ) to measure angles 3 . Divider B ) to measure the length of the line segments
