Special Segments and Center of Triangles

What does the word BISECT mean?

• To cut something into more than five pieces.
• It is a plane with two sets of wings.
• A shape that has three sides. 
• To cut something into two congruent pieces or in half.

Which of the following describes an altitude of a triangle?

• A segment that passes through the middle of the triangle.
• A segment with endpoints at the vertex and midpoint of the opposite side.
• A segment that connects two midpoints of two sides.
• A segment that connects the vertex and the opposite side at 90 degrees. 

A line segment that joins the midpoints of two sides of a triangle, is parallel to the third side and its length is one-half the length of the third side.

• Perpendicular Bisector
• Angle Bisector
• Median
• Midsegment

When you draw the medians of a triangle it creates the point of concurrency called the _____________.

• Centroid
• Incenter
• Perpendicular Bisectors
• Altitude

This point divides a line segment into 2 equal parts.

• point
• vertex
• midpoint
• segment

A line, segment, or ray that divides an angle in half

• Perpendicular bisector
• Vertical angles
• Angle bisector
• Midsegment

Define: INCENTER OF A TRIANGLE

• the point of concurrency of the three angle bisectors of a triangle 
• the point of concurrency of the three medians of a triangle
• the point of concurrency of the three perpendicular bisectors of a triangle 
• the point of concurrency of the three midsegments of a triangle

A line, segment, or ray that passes through the midpoint of a side that is creates a 90 degree angle with that side.

• Perpendicular bisector
• Angle bisector
• Median
• Altitude

Define: CIRCUMCENTER OF A TRIANGLE

• the point of concurrency of the three angle bisectors of a triangle 
• the point of concurrency of the three medians of a triangle
• the point of concurrency of the three perpendicular bisectors of a triangle 
• the point of concurrency of the three midsegments of a triangle

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