If a point is on the bisector of an angle, then it is equidistant from the two sides of the angle-apex
No, it does not.
on the perpendicular bisector
An Angle Bisector
Yes. The bisector of one angle of a triangle is the perpendicular bisector of theopposite side if the bisected angle is the vertex angle of an isosceles triangle,or any angle of an equilateral triangle.
If a point is on the bisector of an angle, then it is equidistant from the two sides of the angle-apex
They are the same concept, one for the angle and 1 for triangle.Definition of a triangle angle bisector is a line segment that bisects one of the vertex angles of a triangle.Definition of an angle bisector is a ray or line segment that bisects the angle, creating two congruent angles.
No, it does not.
converse of the angle bisector theorem
Proposition 3 of Book IV in Euclid's Elements (angle bisector theorem)
The Angle Bisector Theorem states that given triangle and angle bisector AD, where D is on side BC, then . Likewise, the converse is also true. Not sure if this is what you want?
the definition of an angle bisector is a line that divides an angle into two equal halves. So you need only invoke the definition to prove something is an angle bisector if you already know that the two angles are congruent.
Biconditional Statement for: Perpendicular Bisector Theorem: A point is equidistant if and only if the point is on the perpendicular bisector of a segment. Converse of the Perpendicular Bisector Theorem: A point is on the perpendicular bisector of the segment if and only if the point is equidistant from the endpoints of a segment.
on the perpendicular bisector
An angle bisector bisects an angle. A perpendicular bisector bisects a side.
Any shape which has an angle can have an angle bisector.
A segment need not be a bisector. No theorem can be used to prove something that may not be true!
