### Which point of concurrency is the intersection of the medians of a triangle?

• A.

Circumcenter

• B.

Incenter

• C.

Centroid

• D.

Orthocenter

C. Centroid
Explanation
The centroid is the point of concurrency where the medians of a triangle intersect. A median is a line segment that connects a vertex of a triangle to the midpoint of the opposite side. The centroid is located two-thirds of the distance from each vertex to the midpoint of the opposite side. It is often referred to as the center of mass or the balance point of the triangle because it is the point where the triangle would perfectly balance if it were cut out of a uniform material.

### Which point of concurrency is the intersection of the perpendicular bisectors of a triangle?

• A.

Circumcenter

• B.

Incenter

• C.

Centroid

• D.

Orthocenter

A. Circumcenter
Explanation
The circumcenter is the point of concurrency that is formed by the intersection of the perpendicular bisectors of a triangle. The perpendicular bisector of a side of a triangle is a line that is perpendicular to the side and passes through its midpoint. The circumcenter is the center of the circle that circumscribes the triangle, meaning that it is equidistant from all three vertices of the triangle.

### Which point of concurrency is the intersection of the angle bisectors of a triangle?

• A.

Circumcenter

• B.

Incenter

• C.

Centroid

• D.

Orthocenter

B. Incenter
Explanation
The incenter is the point of concurrency that is the intersection of the angle bisectors of a triangle. The angle bisectors are the lines that divide the angles of the triangle into two equal parts. The incenter is the center of the inscribed circle in the triangle, which is the largest circle that can fit inside the triangle. It is equidistant from all three sides of the triangle, making it the point where the angle bisectors intersect.

### Which point of concurrency is the intersection of the altitudes of a triangle?

• A.

Circumcenter

• B.

Incenter

• C.

Centroid

• D.

Orthocenter

D. Orthocenter
Explanation
The orthocenter is the point of concurrency where the altitudes of a triangle intersect. The altitude of a triangle is a line segment drawn from a vertex perpendicular to the opposite side. The orthocenter is important because it is the center of the triangle's orthic triangle, which is formed by the feet of the altitudes. The orthocenter can lie inside, outside, or on the triangle depending on the type of triangle.

### Which point of concurrency is equidistant from the three sides of a triangle?

• A.

Circumcenter

• B.

Incenter

• C.

Centroid

• D.

Orthocenter

B. Incenter
Explanation
The incenter of a triangle is the point of concurrency that is equidistant from the three sides of the triangle. It is the center of the inscribed circle, which touches all three sides of the triangle.

### Which point of concurrency is equidistant from the three vertices of a triangle?

• A.

Circumcenter

• B.

Incenter

• C.

Centroid

• D.

Orthocenter

A. Circumcenter
Explanation
The circumcenter is the point of concurrency that is equidistant from the three vertices of a triangle. It is the center of the circumcircle, which is a circle that passes through all three vertices of the triangle. The circumcenter can be found by finding the intersection of the perpendicular bisectors of the triangle's sides.

### Which point of concurrency is the center of gravity of a triangle?

• A.

Circumcenter

• B.

Incenter

• C.

Centroid

• D.

Orthocenter

C. Centroid
Explanation
The centroid is the point of concurrency that represents the center of gravity of a triangle. It is the point where the three medians of the triangle intersect. The medians are the line segments that connect each vertex of the triangle to the midpoint of the opposite side. The centroid divides each median into two segments, with the segment closer to the vertex being twice as long as the segment closer to the midpoint. This point is often referred to as the "balance point" of the triangle because if the triangle were a physical object, it would balance perfectly on the centroid.

### The centroid is ______________________ inside the triangle.

• A.

Always

• B.

Sometimes

• C.

Never

A. Always
Explanation
The centroid is always located inside the triangle. The centroid is the point of intersection of the medians of a triangle, which are the line segments connecting each vertex to the midpoint of the opposite side. Since the medians always intersect inside the triangle, the centroid is always located inside the triangle.

### The circumcenter is _________________ inside of the triangle.

• A.

Always

• B.

Sometimes

• C.

Never

B. Sometimes
Explanation
The circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect. This point can be located inside the triangle if the triangle is acute, on the triangle if the triangle is right-angled, and outside the triangle if the triangle is obtuse. Therefore, the circumcenter is sometimes inside of the triangle.
