Question 72
Draw the images of the points A, B, and C in the line m (figure). Name them as A`, B` and C` respectively and join them in pairs. Measure AB, BC, CA, A`B`, B`C` and C`A`. Is AB = A`B`, BC = B`C`, and CA = C`A`?
Question 69
Draw the images of points A and B in line l of the figure and name them as A` and B`, respectively. Measure AB and A`B`. Are they equal?
Draw any line segment, say ¯¯¯¯¯¯¯¯AB. Take any point C lying in between A and B. Measure the lengths of AB,BC, and AC. Is AB=AC+CB?
[Note: If A,B,C are any three points on a line, such that AC+CB=AB, then we can be sure that C lies between A and B.]
