Question 2 (a) In Fig. 5.11, mark the parallel lines using the notation given above (single arrow, double arrow etc.). Mark the angle between perpendicular lines with a square symbol. (a) How did you spot the perpendicular lines? You can spot perpendicular lines by looking for corners that form perfect right angles, just like the corner of a square. On the grid paper, these are the points where a horizontal line meets a vertical line. Let’s try marking perpendicular lines with square symbol Question 2 (b) In Fig. 5.11, mark the parallel lines using the notation given above (single arrow, double arrow etc.). Mark the angle between perpendicular lines with a square symbol. (b) How did you spot the parallel lines? You can spot parallel lines by identifying lines which are the same distance apart and will never cross, no matter how long you make them. On the grid, look for: Two or more horizontal lines in the same shape. Two or more vertical lines in the same shape. Two or more diagonal lines that follow the exact same dot pattern (e.g., both go 'up 1, right 2'). Let’s try marking parallel lines with single or double arrow
