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.


What is the orthocenter?

The point at which the lines containing the three altitudes of a triangle intersect
