If two sides of one triangle are congruent to two side of another triangle and the included angle of the first is larger that the included angle of the second, then the 3rd side of the first triangle is longer than the third side of the second.

If two sides of one triangle are congruent to two sides of another triangle, and the third side of the second, then the included angle of the first is larger than the included angle of the second.
point of concurrency
point where three or more lines intersect
point of currency where the perpendicular bisectors of a triangle intersect- equidistant from veritces
point of concurrency where angle bisectors intersect- equidistant from the sides of the triangle
point of concurrency where medians intersect- 2/3 from vertex to centroid
point of concurrency where altitudes intersect
altitude of a triangle
a perpendicular segment from a vertex to the line containing the opposite side
median of a triangle
a segment from a vertex to the midpoint of the opposite side
line that bisects another line and is perpendicular to that line
