CBSE CLASS 9 CHAPTER 6 LINES AND ANGLE || ANGLE MADE BY TRANSVERSAL WITH TWO LINES

Distance and Angle between Two Lines

Two parallel lines AB and CD are intersected by a transversal line EF at M and N, respectively. If the lines MP and NP are the bisectors of the interior angles BMN and DNM on the same side of the transversal, then angleMPN is equal to

Point OF angle || Adjacent angle || Linear pair OF angle || Vertical-opposite angle|| Transversal lines Corresponding angle|| Alternate Interior angle || Co-interior|| Exterior angle || Example discussion

Which of the following statements are true (T) and which are false (F)? Give reasons. (i)If two lines are intersected by a transversal, then corresponding angles are equal. (ii)If two parallel lines are intersected by a transversal, then alternate interior angles are equal. (iii)Two lines perpendicular to the same line are perpendicular to each other. (iv)Two lines parallel to the same line are parallel to each other. (v)If two parallel lines are intersected by a transversal, then the interior angle on the same side of the transversal are equal.

The line n is transversal to line l\ a n d\ m in Fig.61. Identity the angle alternate to /_13 , angle corresponding to /_15 , and angle alternate to /_15.

A line makes angles of measures 60^(0) with y -axis, and 120^(@) with z-axis. Then the angle made by the line with x-axis is
