Studdy Solution

STEP 1

Assumptions1. The circumcenter of a triangle is the point where the perpendicular bisectors of the sides of the triangle intersect. . A circle circumscribing a triangle is a circle that passes through all the vertices of the triangle.
3. A circle inscribed inside a triangle is a circle that touches all the sides of the triangle.
4. The center of mass and balance of a triangle is the point where the medians of the triangle intersect, also known as the centroid.
5. Concurrent constructions are methods used to find points of concurrency in a figure, such as the circumcenter, incenter, and centroid of a triangle.

STEP 2

The circumcenter of a triangle is the point where the perpendicular bisectors of the sides of the triangle intersect. This point is equidistant from the vertices of the triangle and is the center of the circle that circumscribes the triangle. Hence, option B is correct.
Circumcenter=Center of a circle circumscribing the triangle\text{Circumcenter} = \text{Center of a circle circumscribing the triangle}

STEP 3

The circumcenter is not the center of the circle inscribed inside the triangle. The center of the inscribed circle, or incircle, is the incenter of the triangle, which is the intersection of the angle bisectors of the triangle. Hence, option C is incorrect.
CircumcenterCenter of a circle inscribed inside the triangle\text{Circumcenter} \neq \text{Center of a circle inscribed inside the triangle}

STEP 4

The circumcenter is not the center of mass and balance of the triangle. The center of mass and balance, or the centroid, is the intersection of the medians of the triangle. Hence, option D is incorrect.
CircumcenterCenter of mass and balance\text{Circumcenter} \neq \text{Center of mass and balance}

STEP 5

Since the circumcenter is not the center of all the given options, option A is also incorrect.
CircumcenterAll of these\text{Circumcenter} \neq \text{All of these}

STEP 6

To find the circumcenter of a triangle, we need to use the concurrent construction of perpendicular bisectors. The intersection point of the perpendicular bisectors of the sides of a triangle gives the circumcenter.
Hence, the types of concurrent constructions needed to find the circumcenter of a triangle are the perpendicular bisectors of the sides of the triangle.
