I will solve this problem by analyzing the image, which is a worksheet about the "Centers of Triangles." The task requires me to fill in the blanks for each of the four centers: Circumcenter, Incenter, Centroid, and Orthocenter. I'll go through each one systematically.
First, look closely:
The image displays four columns, each dedicated to one of the triangle centers. Each column has two sections:
1.
Created by: This section likely asks for the definition or construction method of the center.
2.
Important Facts: This section provides a sentence with a blank that needs to be filled with the correct term (e.g., "The ____ is equidistant from each vertex...").
By looking at the diagrams, I can see the geometric constructions:
-
Circumcenter: Shows perpendicular bisectors of the sides intersecting at point M.
-
Incenter: Shows angle bisectors intersecting at point M.
-
Centroid: Shows medians (lines from vertices to midpoints of opposite sides) intersecting at point M.
-
Orthocenter: Shows altitudes (perpendicular lines from vertices to opposite sides) intersecting at point M.
The text in the "Important Facts" section gives strong clues:
- For the Circumcenter, it says the blank is "equidistant from each vertex."
- For the Incenter, it says the blank is "equidistant from each side."
- For the Centroid, it describes a line from a vertex to the midpoint.
- For the Orthocenter, it describes a line from a vertex that is perpendicular to the opposite side.
I now have enough information to answer the question without needing to look up external facts, as the image itself provides all the necessary context. I will now provide the completed solution.

Solution:
Here is the completed worksheet based on the definitions and diagrams provided in the image:
Circumcenter
*
Created by: The intersection of the perpendicular bisectors of the sides of the triangle.
*
Important Facts: The
circumcenter is equidistant from each vertex of the triangle.
Incenter
*
Created by: The intersection of the angle bisectors of the triangle.
*
Important Facts: The
incenter is equidistant from each side of the triangle.
Centroid
*
Created by: The intersection of the medians of the triangle.
*
Important Facts: A
median is created by a vertex connected to the midpoint of the opposite side.
Orthocenter
*
Created by: The intersection of the altitudes of the triangle.
*
Important Facts: An
altitude is created by a vertex connected to the opposite side so that it is perpendicular to that side.
