Sometimes. If the triangle is an equilateral triangle, then yes. If the triangle has two sides of equal length, then the bisector passing through the point connecting the two sides of equal length will share the orthocenter. If all three sides have different lengths, then none of the bisectors of a triangle will share (pass through) the orthcenter.
The definition of the orthocenter is:
The point where the three altitudes of a triangle intersect. (An altitude is the line
from a vertex drawn perpendicular to the opposite side.) So an angle bisector
doesn't pass through the orthocenter unless the angle bisector happens to
coincide with the altitude, and that only happens when the triangle is either
isosceles or equilateral.
The angle bisectors always intersect inside the triangle. (This is not true for altitudes and right bisectors.)
Angle bisectors are.
In general, they are not. In an isosceles triangle, the perpendicular bisector of the base is the same as the bisector of the angle opposite the base. But the other two perp bisectors are not the same as the angle bisectors. Only in an equilateral triangle is each perp bisector the same as the angle bisector of the angle opposite.
The common intersection of the angle bisectors of a triangle is called the incenter. It is the center of the inscribed circle of the triangle, and is equidistant from the three sides of the triangle.
The point in which all the angle bisectors intersect is called the incenter.
Actually, the orthocenter of a triangle is the point where the three altitudes of the triangle intersect. The altitudes are perpendicular lines drawn from each vertex to the opposite side. The angle bisectors of a triangle intersect at the incenter, not the orthocenter.
Orthocenter My improvement: The three angle bisectors will intersect at a point called the incenter. At this point it also the center of the largest possible circle within the triangle. Since a circle has a center point, this point within the triangle is called the incenter. The three heights of a triangle will meet at a special point called the orthocenter.
Objection! False! Nooo! :P ~
In a obtuse triangle, the point of concurrency, where multiple lines meet, of the altitudes, called the orthocenter, is outside the triangle. In a right angle, the orthocenter lies on the vertex (corner) of the right angle. In an acute angle, the orthocenter lies inside the triangle.
equilateral triangle
The angle bisectors of a triangle are the lines which cut the inner angles of a triangle into equal halves. The angle bisectors are concurrent and intersect at the center of the incircle.
The angle bisectors always intersect inside the triangle. (This is not true for altitudes and right bisectors.)
The name of the point at which all of a triangle's angle bisectors converge is the incenter.
Angle bisectors intersect at the incenter which is equidistant from the sides
At the vertex of the right angle.
The point in a triangle where all three angle bisectors meet is called the incenter.
The 3 angle bisectors of a triangle intersect in a point known as the INCENTER.
