WebThe incenter is the point of concurrency of the angle bisectors of all the interior angles of the triangle. In other words, the point where three angle bisectors of the angles of the triangle meet are known as the incenter. The incenter always lies within the triangle. 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: Centroid Draw a line (called a "median") from each corner to the midpoint of the opposite side. See more 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? See more Try this: drag the points above until you get a right triangle (just by eye is OK). Where is the circumcenter? Why? See more 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.
