Is line segment AD or DC larger?
Line segment DC
300
Where is the circumcenter for obtuse angles?
Outside the triangle
300
What special property does the centroid have?
the centroid is 2/3 of the distance from each vertex and 1/3 the distance to the middle of opposite side
300
What is the side-angle relationship?
The largest side of a triangle is directly opposite of the largest angle

Perpendicular Bisector Theorem
Any point on the perpendicular bisector is equidistant from the endpoints of the segments
400
How is median different from perpendicular bisectors?
The median starts at the vertex and goes to the midpoint of the opposite side. The perpendicular bisector starts and midpoint and creates a 90 degree angle.

List the sides of the triangle from smallest to largest
Line segment YX, YZ, and XZ

What is the triangle inequality theory?
The sum of the lengths of any two sides must be greater than the remaining sides.

What is the converse of hinge?
if two triangles have two congruent sides, then the triangle with the longer third side will have a larger angle opposite that third side.
500
Point of Concurrency for the angle bisectors is called....
Incenter
500
Is the centroid theorem for median, altitudes, or both
Just medians

What is the largest whole number side measurement for the third side of a triangle with given sides of 18 and 24
41

What is the hinge theorem?
if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first triangle is longer than the third side of the second triangle.
