Find the midpoint of a side and join it to the vertex opposite. That is a median and it divides the mass of a triangle in two halves. Each triangle has three medians.
However, there is no reason for a bisector to go through a vertex - it can be a straight line through any point in the triangle. In such a case drawing the bisector analytically is likely to be beyond the skills of most geometry students. There is, though, a very simple practical solution.
Cut out a copy of the triangle on a uniform lamina. Suspend it vertically by a pin through the required point. Then the vertical line through that point (use a plumb line) is the bisector of the triangle through that point.

Is a perpendicular bisector always an angle bisector?
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! =)
How is constructing a perpendicular bisector different to constructing an angle bisector?
A perpendicular bisector is a straight line that divides a side of a triangle in two and is at right angles to that side. An angle bisector is a straight line that divides an angle of a triangle in two.
Will a angle bisector determine a midpoint?
If you perform an angle bisector on an angle in a triangle, then it will go through the midpoint of the opposite side.
What splits an angle of the triangle into two congruent parts?
An angle bisector.
Is it true that the perpendicular bisector of the base of an isosceles triangle splits the triangle into two congruent triangles?
Yes, it is true.
The first step in the construction of a perpendicular bisector is to draw a?
equilateral triangle ;)
Can the angle bisector of a triangle also be the perpendicular 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.
How do you draw an angle bisector?
Draw an L and draw a line coming from the origin of the angle. That dividing line is an angle bisector.
Is the height of a triangle a bisector?
No.
What triangle must always have at least one angle bisector that is also a perpendicular bisector?
any isosceles triangle

What do you call the intersection of a triangle angle bisector?
triangles angle bisector is called incenter..
Could the median of a triangle be the perpendicular bisector?
Yes in equilateral triangle.
What is the proof that equiangular triangle is also called equilateral triangle?
Label the triangle ABC. Draw the bisector of angle A to meet BC at D. Then in triangles ABD and ACD, angle ABD = angle ACD (equiangular triangle) angle BAD = angle CAD (AD is angle bisector) so angle ADB = angle ACD (third angle of triangles). Also AD is common. So, by ASA, triangle ABD is congruent to triangle ACD and therefore AB = AC. By drawing the bisector of angle B, it can be shown that AB = BC. Therefore, AB = BC = AC ie the triangle is equilateral.
Is the altitude of a triangle always the perpendicular bisector?
No.
How many angle bisector has a triangle?
