100
The medians of a triangle go from the ________________ to the midpoint of the opposite side.
The medians of a triangle go from the (Vertex) to the midpoint of the opposite side.
100
What is the rule for the centroid? The segment from the vertex to the centroid is _____________ the length from the centroid to the ______________.
The segment from the vertex to the centroid is (Twice or two times) the length from the centroid to the (midpoint)
100
What is the difference between an altitude and a perpendicular bisector?
Altitudes go through the vertex and form a right angle and Perpendicular Bisectors go through the midpoint and form a right angle.
100
What is an angle bisector?
the line that cuts on of the angles in a triangle into two equal pieces
100
What is the name of the point where all three medians in a triangle meet?
Centroid
200
Which segment in the image if the median?
AC
200
RU = 14.6
200
Altitude, Perpendicular Bisector, or neither?
Altitude, because it goes from the vertex and forms a right angle. 
200
m < 1 = 48 degrees
200
What is the point called where all three altitudes meet in a triangle?
orthocenter
300
Z = 6 so that helps us find RT which is 11
300
EF = 8.5
300
Altitude, Perpendicular Bisector, or neither
Perpendicular Bisector, because goes through the midpoint and forms a right angle. 
300
M < 1 = 25 degrees
300
what is the point called where all three perpendicular bisectors meet?
circumcenter
400
x = 2 which helps you find < PSR = 72 degrees
400
Find the length of MP.
MP = 15
400
Altitude, Perpendicular Bisector, or neither
Altitude, because it goes through the vertex and forms a right angle
400
< ACB = 62 degrees
400
What is the point called where all three angle bisectors meet?
incenter
500
RW = 14
500
