|
What is does midsegment of a triangle mean?
|
Connects the midpoints of two sides of a triangle.(Every triangle has three midsegments)
|
|
|
Cordinate Proof
|
involves placing geometric figures in a coordinate plane. (When you use variables to represent the coordinates of a figure in a coordinate proof, the results are true for all figures of that type)
|
|
|
What is a Perpendicular Bisector?
|
A segment, ray, line, or plane that is perpendicular to a segment at its midpoint. (kind of like this symbol...+)
|
|
|
What does it mean to be *equi*distant?
|
To have equal or the same distance
|
|
|
What is the point of concurrency?
|
The point of intersection of the lines, rays, or segments.
|
|
|
What is the circumcenter of a triangle?
|
It is the point of concurrency of the three perpendicular bisectors of a triangle.
|
|
|
What is the incenter of the triangle?
|
The point of concurrency of the three angle bisectors of a triangle
|
|
|
What is the median of a triangle?
|
It is the segment from a vertex to the midpoint of the opposite side.
|
|
|
Centroid.
|
Its the point of concurrency, which is inside of the triangle
|
|
|
What is the Altitude of a Triangle?
|
The perpendicular segment from a vertex to the opposite side or to the line that contains the opposite side
|
|
|
What is the orthocenter?
|
The point at which the lines containing the three altitudes of a triangle intersect
|
|
|
Explain what an indirect proof is?
|
a proof in which you prove that a statement is true by first assuming that its opposite is true. If this assumption leads to an impossibility, then you have proved that the original statement is true.
