true
This statement is false. A perpendicular bisector is not enough to make the statement true.
thank goodness for my math teacher, norm! he said only in an isosceles triangle. The bisector of the vertex angle of an isosceles triangle is perpendicular to the base! =)
yes
always
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?
true
True
The angle bisectors always intersect inside the triangle. (This is not true for altitudes and right bisectors.)
A Line Bisector
Ray BD is a bisector of angle EBA.
Not always because a perpendicular bisector can be constructed with compasses
The bisector and the line segment are perpendicular to each other.
True
No.
Not sure what an "irie" is. But a bisector does not need to be perpendicular.
iscoceles triangle! =)
