(a) Two lines AB and CD is shown above. Make the two lines parallel by adjusting their end points onto corners of squares on the main grid lines.
(b) After adjusting the two lines, do they intersect at any point? (even if the lines were to be extended)
(c) Is there an equal number of square boxes between the two lines?
(d) Using a ruler and set square to measure, are the two lines same distance at all points between one another?
Two lines AB and CD is shown above. Make the two lines perpendicular by adjusting their end points onto intersecting points on the square grid.
(a) Did these two lines intersect with one another?
(b) Did these two lines meet at the corner of a square grid?
(c) Using a protractor to measure, are these two lines found to be perpendicular?
