Special Segment Vocab Practice

Front

What is a perpendicular bisector of a triangle?

Back

A segment that is perpendicular to the side of a triangle at its midpoint.

Front

What is a ray that divides an angle into two congruent angles called?

Back

Angle Bisector.

Front

What type of lines are perpendicular bisectors?

Back

Lines that intersect a segment at its midpoint and form right angles with it.

Front

What is an angle bisector?

Back

A segment that divides an angle into two equal parts.

Front

What is a median in a triangle?

Back

A segment that connects a vertex to the midpoint of the opposite side.

Front

What is the definition of an altitude in a triangle?

Back

A segment from a vertex perpendicular to the line containing the opposite side.

Front

What does the term 'segment bisector' refer to?

Back

A point, ray, line, or segment that divides another segment into two equal parts.

Front

What is the relationship between a median and the centroid of a triangle?

Back

The centroid is the point where all three medians intersect.

Front

How do you find the length of a median in a triangle?

Back

Use the formula: Median = 1/2 * sqrt(2a^2 + 2b^2 - c^2), where a and b are the lengths of the sides adjacent to the median and c is the length of the opposite side.

Front

What is the significance of the circumcenter in a triangle?

Back

The circumcenter is the point where the perpendicular bisectors of the sides intersect, and it is equidistant from all vertices.
