Question 4 - Think & Reflect (Page 95) As you go along the perpendicular bisector, will the circle drawn from that point through A and B appear more curved or less curved? Let’s try to do move centers Thus, the circle drawn looks Less curved. As a circle gets gigantic, its boundary looks flatter and flatter. Think about the Earth—it’s a giant sphere, but to us standing on it, it looks flat!
