Question 1 - Figure it out (Page 142) Justify why AB in Fig. 6.4 is the perpendicular bisectorThink about Symmetry: When you pulled the rope tight to make Point A, the rope length on the left (from ð to ðŽ ) was exactly the same as the rope length on the right (from ð to ðŽ ). This created a perfectly balanced Triangle (an isosceles triangle). The same thing happened at the bottom for Point B. Because A and B are both perfectly balanced between X and Y , the line connecting them must go straight down the middle! In geometry, the line connecting the tips of two back-to-back isosceles triangles (a kite shape) always crosses the middle at 90^â. Thus, AB is Mid-point of XY Crosses at 90° ⎠AB is the perpendicular bisector
