What is a Triangle Bisector?
A triangle bisector is a line segment or ray that divides a triangle into two equal parts. A triangle bisector can also be used to divide an angle of a triangle into two equal angles. In a triangle, each vertex has two associated bisectors: one from the opposite side and one from the adjacent side. Bisectors are important because they can be used to solve many triangle problems.
Types of Triangle Bisectors
There are five main types of triangle bisectors: the angle bisector, the median, the altitude, the perpendicular bisector, and the centroid. Each type of bisector is used for different purposes and can help to solve a variety of triangle problems. It is important to understand the different types of bisectors and how they are used.
Angle Bisector
The angle bisector is a line that divides the angle of a triangle into two equal angles. The angle bisector passes through the vertex of a triangle and bisects the angle into two equal angles. This type of bisector is useful when finding the area of a triangle or when solving a triangle with no side lengths given.
Median
The median is a line that passes through the midpoint of a side of a triangle and connects it to the opposite vertex. The median bisects the side of a triangle and divides it into two equal parts. This type of bisector is useful for finding the area of a triangle or for solving a triangle with two sides given.
Altitude
The altitude is a line that passes through a vertex of a triangle and is perpendicular to the opposite side. This type of bisector is useful for finding the height of a triangle, or for solving a triangle with two angles and one side given. The altitude bisects the angle opposite to the side it is drawn from.
Perpendicular Bisector
The perpendicular bisector is a line that passes through the midpoint of a side of a triangle and is perpendicular to that side. This type of bisector divides the side of a triangle into two equal parts. This type of bisector is useful for solving a triangle with two sides and an angle given.
Centroid
The centroid is a point within a triangle that is the intersection of the three medians. The centroid bisects each median and divides the triangle into three equal parts. This type of bisector is useful for finding the center of mass of a triangle or for solving a triangle with three sides given.
Triangle bisectors are important for solving triangle problems.
