Are a, b and c parallel to p, q and r respectively? Why or why not? Class 7
mediumAre a, b and c parallel to p, q and r respectively? Why or why not? Class 7
Question 1.
Are a, b and c parallel to p, q and r respectively? Why or why not? Class 7
Solution:
Yes. Reasons for it are based on the properties of parallel lines which are being discussed in later part of this chapter.
Question 2.
Draw some lines perpendicular to the lines given on the dot paper in Fig. Class 7
Solution:
Some perpendicular lines have been drawn in the given figure.
Question 3.
In Fig., mark the parallel lines using the notation given above (single arrow, double arrow etc.). Mark the angle between perpendicular lines with a square symbol. Class 7
(a) How did you spot the perpendicular lines?
(b) How did you spot the parallel lines?
Solution:
Arrows have been marked in the figure for parallel lines and square have been marked for perpendicular lines in the figure as shown.
(a) We have spotted the perpendicular lines by taking horizontal and vertical lines.
(b) Parallel lines have been spotted by taking pairs of horizontal lines and pairs of vertical lines. Parallel lines have also been spotted by intuition.
