Question

What are the differences between a median and a perp. bisector?

Answer 1

@andies I have answered your question about a=1absin(theta)

Answer 2

This didn't help. Please explain without numbers

Answer 3

The median of the triangle is a segment that connects the vertex of the triangle to the midpoint of the side opposite to the vertex.The perpendicular bisector of the triangle is a segment that connects the vertex of the triangle to the side opposite to the triangle, that intersects that side at exactly 90° at its midpoint.

The perpendicular bisector is half median and half altitude.
