Study Notes
Points of Concurrency
- Four key points of concurrency: Circumcenter, Incenter, Centroid, and Orthocenter.
- Circumcenter is formed by the intersection of Perpendicular Bisectors of the sides of a triangle.
- Incenter is created by the intersection of Angle Bisectors, representing equal distance to the triangle's sides.
- Centroid is formed by the intersection of Medians, which connect a vertex to the midpoint of the opposite side.
- Orthocenter is defined by the intersection of Altitudes, lines drawn from a vertex perpendicular to the opposite side.
Definitions and Concepts
- A Point of Concurrency is where three or more lines intersect.
- Lines that meet at a single location are termed Concurrent.
Types of Lines in Triangles
- An Angle Bisector divides an angle into two equal angles, originating from a vertex.
- A Perpendicular Bisector is a line that intersects a segment at its midpoint at a right angle.
- An Altitude extends from a vertex to the opposite side, forming a right angle with that side.
- A Median connects a vertex to the midpoint of the opposing side.
Theorems Related to Triangles
- Triangle Midsegment Theorem: A segment connecting midpoints of two sides is parallel to the third side, and its length is half that of the third side.
- Perpendicular Bisector Theorem: A point on the perpendicular bisector of a segment is equidistant from both endpoints of that segment.
- Converse of the Perpendicular Bisector Theorem: If a point is equidistant from the endpoints of a segment, it lies on the segment's perpendicular bisector.
- Angle Bisector Theorem: A point on the bisector of an angle is equidistant from the sides of the angle.
- Converse of the Angle Bisector Theorem: If a point inside an angle is equidistant from the angle's sides, it is located on the angle bisector.
- Concurrency of Medians Theorem: The intersection of the medians occurs at a point that is two-thirds of the distance from each vertex to the midpoint of the opposite side.
