Triangle Centers
Where is the center of a triangle?
There are actually thousands of centers!
Here are the 4 most popular ones:
Centroid, Circumcenter, Incenter and Orthocenter
For each of those, the "center" is where special lines cross, so it all depends on those lines !
Let's look at each one:
Try this: cut a triangle from cardboard, draw the medians. Do they all meet at one point? Can you balance the triangle at that point?
Fun fact: The centroid divides each median in the ratio 2 : 1
Circumcenter
Try this: drag the points above until you get a right triangle (just by eye is OK). Where is the circumcenter? Why?
Try this: find the incenter of a triangle using a compass and straightedge at: Inscribe a Circle in a Triangle
Orthocenter
Note that sometimes the edges of the triangle have to be extended outside the triangle to draw the altitudes. Then the orthocenter is also outside the triangle.

Draw a line segment (called the "altitude") at right angles to a side that goes to the opposite corner. Note that sometimes the edges of the triangle have to be extended outside the triangle to draw the altitudes. Then the orthocenter is also outside the triangle. Learn about the many centers of a triangle such as Centroid, Circumcenter and more.
Orthocenter. The point at which the altitudes of a triangle intersect. In interior if acute, In exterior if obtuse, at right angle if right. Inequality. For any real numbers a and b, a > b if and only if there is a positive number c, such that a = b + c. Properties of Inequality. Comparison Property: a < b, a > b, a = b, a ≤ b, a ≥ b.
The incenter of a triangle is the point at which the three angle bisectors intersect. To locate the incenter, one can draw each of the three angle bisectors, and then determine the point at which they all intersect. The incenter is also notable for being the center of the largest possible inscribed circle within the triangle.
Instruction Incenter and Circumcenter Inscribing a Circle in a Triangle • Construct the angle bisector of each angle. The point of concurrency is the incenter. • Construct a perpendicular line from the incenter to one of the sides. • Place the compass point on the incenter and the pencil point at the intersection

The circumcenter, the orthocenter, the incenter, and the centroid are points that represent the intersections of different internal segments of a triangle. For example, we can obtain intersection points of perpendicular bisectors, bisectors, heights and medians. In this article, we will explore the circumcenter, orthocenter, incenter, and ...
