Altitude of a triangle | Perpendicular segment from a vertex of the triangle to the line containing the opposite side |
Centroid | Point of concurrency of the medians |
Circumcenter of a triangle | Point of concurrency of the perpendicular bisectors of a triangle |
Concurrent | When three or more lines intersect at one point |
Equidistant | Same distant from the objects |
Incenter | Center of a circle inscribed in a triangle |
Indirect proof | A proof involving indirect reasoning |
Median | Segments whose endpoints are a vertex and the midpoint of the opposite side |
Mid-segment of a triangle | Segment connecting the midpoints of two sides of a triangle |
Orthocenter | A point the lines that contain the altitudes of a triangle are concurrent at |
Distance from a point to a line | Length of the perpendicular segment from the point to the line |
