If you only explain one that is fine

The centroid of a triangle is constructed by taking any given triangle and connecting the midpoints of each leg of the triangle to the opposite vertex. The line segment created by connecting these points is called the median. No matter what shape your triangle is, the centroid will always be inside the triangle. The centroid is the center of a triangle that can be thought of as the The circumcenter is the center of the circle such that all three vertices of the circle are the same distance away from the circumcenter. Thus, the circumcenter is the point that forms the origin of a circle in which all three vertices of the triangle lie on the circle. Thus, the radius of the circle is the distance between the circumcenter and any of the triangle's three vertices. It is found by finding the midpoint of each leg of the triangle and constructing a line perpendicular to that leg at its midpoint. Where all three lines intersect is the circumcenter. The circumcenter is not always inside the triangle. In fact, it can be outside the triangle, as in the case of an obtuse triangle, or it can fall at the midpoint of the hypotenuse of a right triangle. You see that even though the circumcenter is outside the triangle in the case of the obtuse triangle, it is still equidistant from all three vertices of the triangle. The orthocenter is the center of the triangle created from finding the altitudes of each side. The altitude of a triangle is created by dropping a line from each vertex that is perpendicular to the opposite side. An altitude of the triangle is sometimes called the height. Remember, the altitudes of a triangle do not go through the midpoints of the legs unless you have a special triangle, like an equilateral triangle. Like the circumcenter, the orthocenter does not have to be inside the triangle. The incenter is the last triangle center we will be investigating. It is the point forming the origin of a circle inscribed inside the triangle. Like the centroid, the incenter is always inside the triangle. It is constructed by taking the intersection of the angle bisectors of the three vertices of the triangle. The radius of the circle is obtained by dropping a perpendicular from the incenter to any of the triangle legs. There is an interesting relationship between the centroid, orthocenter, and circumcenter of a triangle. The centroid, orthocenter, and circumcenter all fall in a straight line. The centroid is always between the orthocenter and the circumcenter. The distance between the centroid and the orthocenter is always twice the distance between the centroid and the circumcenter. In obtuse triangles, the circumcenter is always outside the triangle opposite the largest angle. The orthocenter is always outside the triangle opposite the longest leg, on the same side as the largest angle. The only time all three of these centers fall in the same spot is in the case of an equilateral triangle. In fact, in this case, the incenter falls in the same place as well.
