You got Homework from your tutor that, how can you draw a triangle that will have exactly two equal length sides or what if you need to find the centre of a circle that passes through a given set of points?
It turns out that a single line called the perpendicular bisector can be useful in both these problems.
The given statements show how perpendicular bisector of a line segment AB behaves:
Statement 1: Cut the line segment AB into two equal pieces.
Statement 2 : Makes 180° angle with the line segment AB.
