Orthocenter, Centroid, Circumcenter and Incenter of a Triangle

Beyond precision

Question: Expert Answer 1 It is the intersection point of the angle bisector of a triangle. We all have seen triangles in our day to day life. Then the formula given below can be used to find the incenter I of the triangle is given by. These are the properties of a triangle: A triangle has three sides, three angles, and three vertices.

Triangles have amazing properties! Among these is that the angle bisectors, segment perpendicular bisectors, medians and altitudes all meet with the rest of their kind. In this worksheet you can move around the vertices of a triangle and see how the different points move. In a triangle, there are 4 points which are the intersections of 4 different important lines in a triangle. They are the Incenter, Orthocenter, Centroid and Circumcenter.

The orthocenter is the point of intersection of the three heights of a triangle. A height is each of the perpendicular lines drawn from one vertex to the opposite side or its extension. The centroid is the point of intersection of the three medians. A median is each of the straight lines that joins the midpoint of a side with the opposite vertex. The centroid divides each median into two segments , the segment joining the centroid to the vertex is twice the length of the length of the line segment joining the midpoint to the opposite side. The circumcenter is the point of intersection of the three perpendicular bisectors. A perpendicular bisectors of a triangle is each line drawn perpendicularly from its midpoint.

For each of those, the "center" is where special lines cross, so it all depends on those lines! Draw a line called a "median" from each corner to the midpoint of the opposite side. Where all three lines intersect is the centroid , which is also the "center of mass":. 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? Try this: drag the points above until you get a right triangle just by eye is OK.

The paper discusses technology that can help students master four triangle centers -- circumcenter, incenter, orthocenter, and centroid. The technologies are a collection of web-based apps and dynamic geometry software. Through use of these technologies, multiple examples can be considered, which can lead students to generalizations about triangle centers. The four most commonly taught triangle centers— incenter, centroid, circumcenter, and orthocenter— can be difficult for students to visualize and understand. Seeing multiple examples can lead students to make and test relevant hypotheses regarding which centers must be inside the triangle incenters and centroids and which can be inside, on, or outside of triangles circumcenters and orthocenters.

    Orthocenter of the triangle is the point of intersection of the altitudes. Like circumcenter, it can be inside or outside the triangle as shown in the figure below.

    Write if the point of concurrency is inside, outside, or on the triangle. Acute ∆. Obtuse ∆. Right ∆. Circumcenter. Incenter. Centroid. Orthocenter.
