Math chapter 5 vocabulary Flashcards
When a point is the same distance from two or more objects.
Equidistant
A set of points that satisfies a given condition.
Locus
When three or more lines intersect at one point.
Concurrent
The point where they intersect.
Point of concurrency
The point of concurrency when three perpendicular bisectors of a triangle are concurrent.
Circumcenter of the triangle
A circle that contains all the vertices of a polygon.
Circumscribed
A circle in a polygon intersects each line that contains a side of the polygon at exactly one point.
Inscribed
The point of concurrency when the angle bisectors of a triangle are also concurrent.
Incenter of the triangle
A segment whose endpoints are a vertex of the triangle and the midpoint of the opposite side.
Median of a triangle
The point of concurrency of the medians of a triangle.
Centroid of the triangle
A perpendicular segment from a vertex to the line containing the opposite side.
Altitude of a triangle
The point of concurrency when the lines containing the altitudes are concurrent at P.
Orthocenter of the triangle
A segment that joins the midpoints of two sides of the triangle.
Midsegment of a triangle
You begin by assuming that the conclusion is false.
Indirect proof
A set of three nonzero whole numbers a,b, and c such that a2+b2=c2
Pythagorean triple
