Triangle Special Segments

Front

What is an angle bisector in a triangle?

Back

An angle bisector is a segment that divides an angle into two equal parts.

Front

What is a median in a triangle?

Back

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

Front

What is an altitude in a triangle?

Back

An altitude is a segment from a vertex of a triangle that is perpendicular to the line containing the opposite side.

Front

What is a perpendicular bisector in a triangle?

Back

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

Front

How many medians does a triangle have?

Back

A triangle has three medians, one from each vertex.

Front

What is the relationship between the angle bisector and the opposite side?

Back

The angle bisector divides the opposite side into two segments that are proportional to the lengths of the other two sides.

Front

What is the centroid of a triangle?

Back

The centroid is the point where the three medians of a triangle intersect.

Front

What is the orthocenter of a triangle?

Back

The orthocenter is the point where the three altitudes of a triangle intersect.

Front

What is the circumcenter of a triangle?

Back

The circumcenter is the point where the three perpendicular bisectors of a triangle intersect.

Front

What is the incenter of a triangle?

Back

The incenter is the point where the three angle bisectors of a triangle intersect.
