Study Notes
Geometry Key Concepts
-
Equidistant: Figures or points that are the same distance apart from each other.
-
Perpendicular Bisector Theorem: A point located on the perpendicular bisector of a segment is equidistant from the segment's endpoints.
-
Converse of the Perpendicular Bisector Theorem: A point that is equidistant from the endpoints of a segment must lie on the segment's perpendicular bisector.
-
Angle Bisector Theorem: A point located on the bisector of an angle is equidistant from the two sides of that angle.
-
Converse of the Angle Bisector Theorem: A point that is equidistant from the sides of an angle lies on that angle's bisector.
-
Concurrent: Describes when three or more lines, rays, or segments intersect at a single point.
-
Point of Concurrency: The specific point where concurrent lines, rays, or segments meet.
-
Circumcenter of a Triangle: The point where the perpendicular bisectors of a triangle intersect, also equidistant from all triangle vertices.
-
Circumcenter Theorem: The circumcenter is equidistant from all vertices of a triangle.
-
Incenter: The point where the angle bisectors of a triangle intersect, also equidistant from all triangle sides.
-
Incenter Theorem: The incenter is equidistant from all sides of the triangle it belongs to.
-
Median of a Triangle: A line segment connecting a vertex of the triangle to the midpoint of the opposite side.
-
Centroid of a Triangle: The intersection point of a triangle’s medians.
-
Centroid Theorem: The centroid divides each median into two segments in a 2:1 ratio, with the longer segment being closer to the vertex.
-
Altitude of a Triangle: A perpendicular line segment drawn from a vertex to the opposite side or its extension.
-
Orthocenter of a Triangle: The intersection point of the three altitudes of a triangle.
-
Midsegment of a Triangle: A segment connecting the midpoints of two sides of a triangle.
-
Triangle Midsegment Theorem: A midsegment of a triangle is parallel to the third side and its length is half that of the third side.
-
Indirect Proof: A method of proving a statement by assuming it is false and demonstrating a contradiction.
-
Triangle Longer Side Theorem: If one side of a triangle is longer than another, the angle opposite the longer side is larger than the angle opposite the shorter side.
-
Triangle Larger Angle Theorem: If one angle of a triangle is greater than another, the side opposite the larger angle is longer than the side opposite the smaller angle.
-
Triangle Inequality Theorem: States that the sum of any two sides of a triangle is greater than the length of the third side.
-
Hinge Theorem: If two sides of one triangle are congruent to two sides of another triangle, and the angle between the first triangle's sides is larger than the angle between the second triangle's sides, then the third side of the first triangle is longer.
-
Converse of the Hinge Theorem: If two sides of one triangle and the third side of another are compared, and the first side is longer, the included angle of the first triangle is larger than that of the second.
