Ch. 6 First Quiz Flashcards
Equidistant
Same distance around the figure
Perpendicular Bisect Theorem
If a point is on a perpendicular bisect of a segment, then the point is equidistant from the ends of the segment.
Converse Perpendicular Bisect Theorem
If a point is equidistant from the end points of a segment, then it lies on the perpendicular bisector of the segment.
Angle Bisector Theorem
If a point is on the bisect of an angle, then the point is equidistant from the sides of the triangle.
Converse Angle Bisector Theorem
If a point is equidistant from the sides of an angle, then the point lies on the angle bisector.
Concurrent Lines
Lines that intersect at the same point
Point of Concurrency
Point where concurrent lines meet
Circumcenter
The pt. concurrency of PERPENDICULAR BISECTORS
Circumcenter Theorem
The circumcenter of a triangle is equidistant from the vertices of the triangle.
The circumcenter is the center of a circle that goes !around! the triangle.
Incenter
The point of concurrency of angle bisectors.
Incenter Theorem
The incenter of a triangle is equidistant from the sides of a triangle.
The incenter is the center of a triangle that goes !inside! the triangle.
Median of Triangle
A segment that starts at a vertex and ends at the midpoint of a side of a triangle.
Centroid
The point of concurrency of medians.
Centroid Theorem
The medians of a triangle intersect to form a point that is 2/3 the distance from the vertex to the midpoint of the opposite side.
Centroid Theorem
The medians of a triangle intersect to form a point that is 2/3 the distance from the vertex to the midpoint of the opposite side.
