1
Q
mid segment
A
- a segment that connects the midpoint of two sides of a triangle
- mid segment is parallel to the third side of the triangle and 1/2 as long
- double the mid segment equals the third side of the triangle
2
Q
point of concurrency
A
the point where three or more lines intersect
3
Q
circumcenter
A
- where the perpendicular bisectors of the three sides of the triangle meet
- the perpendicular bisectors do not originate from the vertices
- is an equal distance from each of the vertices of the triangle
- always appears in the hypotenuse
4
Q
incenter
A
- the point of concurrency of the angle bisectors of a triangle
- the angle bisectors originate from the vertices
- the incenter is an equal distance from each of the sides of the triangle
5
Q
median
A
- a segment from the vertex to the midpoint of the opposite side of a triangle
- the medians originate from the vertices
- the median may or may not be perpendicular the opposite side
6
Q
centroid
A
- the point of concurrency of the three medians of a triangle
- the centroid is two thirds the distance of the whole median as measured from the vertex
- measure of the distance from the centroid to the midpoint of the opposite side is one third the distance of the entire median
- the short part of the median is one half the distance of the long part of the median
7
Q
altitude
A
- the perpendicular segment from a vertex to the opposite side of the triangle
- the altitudes originate from the vertices
- the altitudes may or may not bisect the opposite side
8
Q
orthocenter
A
- the orthocenter is the point of concurrency of the three altitudes of a triangle
- in a right triangle, the orthocenter is the vertex forming the right angle
