Front

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

Front

Define a perpendicular bisector.

Back

A perpendicular bisector is a line that divides a segment into two equal parts at a 90-degree angle.

Front

What is an angle bisector?

Back

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

What is the relationship between the medians of a triangle?

Back

The three medians of a triangle intersect at a point called the centroid, which divides each median into a ratio of 2:1.

What is the significance of the centroid in a triangle?

Back

The centroid is the center of mass of the triangle and is the point where the three medians intersect.

How can you identify an altitude in a triangle?

Back

An altitude can be identified as the segment that forms a right angle with the base of the triangle.
