The centroid is the point of concurrency of the 3 ____ of a triangle. 

• Medians
• Midsegments
• Perpendicular Bisectors
• Angle Bisectos

The figure is an example of a(n) ...

• altitude 
• perpendicular bisector
• midsegment
• angle bisector

The figure is an example of a(n) ...

• angle bisector
• perpendicular bisector
• median
• midsegment

The centroid cuts each median into two segments.  The shorter segment is ___________ the length of the entire segment.

• one third
• two thirds
• three fourths
• one half

If DA is the perpendicular bisector or EI, then

• <IAD and <DAE are right angles
• DI=DE
• EA=IA
• All of the above

• JM = 5

• JM = 10

• JM = 12

• JM = 24

What is the length of DC

• 4
• 1
• 2
• 3

Find x, then the measure of JK

• x=10, JK=50
• x=10, JK=100
• x=15, JK=100
• x=15, JK=50
