Special Segments in Triangles

Front

What is an altitude in a triangle?

Back

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

Front

What does an angle bisector do?

Back

An angle bisector splits 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 the triangle to the midpoint of the opposite side.

Front

What is a perpendicular bisector?

Back

A perpendicular bisector is a segment that is perpendicular to a side of the triangle and divides it into two equal parts.

Front

Identify the segment that represents an altitude in a triangle.

Back

The altitude is the segment that is perpendicular to the opposite side.

Front

Identify the segment that represents a median in a triangle.

Back

The median connects a vertex to the midpoint of the opposite side.

Front

Identify the segment that represents an angle bisector in a triangle.

Back

The angle bisector divides the angle into two equal angles.

Front

Identify the segment that represents a perpendicular bisector in a triangle.

Back

The perpendicular bisector divides a side into two equal segments at a right angle.

Front

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

Back

A median connects a vertex to the midpoint of the opposite side, thus dividing the triangle into two smaller triangles of equal area.

Front

How many medians does a triangle have?

Back

A triangle has three medians, one from each vertex.
