Front

What is the perpendicular bisector?

Back

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

Front

What is the angle bisector?

Back

A line that divides an angle into two equal angles.

Front

What is the median of a triangle?

Back

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

Front

What is the altitude of a triangle?

Back

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

Front

What is the centroid of a triangle?

Back

The point where the three medians intersect, dividing each median into a 2:1 ratio.

Front

What is the circumcenter of a triangle?

Back

The point where the three perpendicular bisectors of the sides intersect.

Front

What is the incenter of a triangle?

Back

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

Front

What is the orthocenter of a triangle?

Back

The point where the three altitudes of a triangle intersect.

Front

How do you find the centroid of a triangle?

Back

By averaging the coordinates of the vertices of the triangle.

Front

What is the relationship between the circumcenter and the circumcircle?

Back

The circumcenter is the center of the circumcircle, which passes through all vertices of the triangle.
