Medians And Altitudes Of Triangles Worksheet Answers – Did you know that three lines of a triangle intersect to form the center of the triangle? And that the centroid is the common point or center of the triangle!
In today’s geometry lesson, we will use this new information to find side lengths and missing angles.
Medians And Altitudes Of Triangles Worksheet Answers
The median is the segment from the vertex of the triangle to the midpoint of the opposite side. And every triangle has three medians.

Also, the co-point, or centroid, of all three centers is two-thirds of the way from each vertex to the center of the opposite side. This is called the centroid theorem or the theorem of the center of symmetry, as ck-12 rightly points out.
Therefore, by understanding the centroid of a triangle and using the centroid theorem, we can find the lengths of the missing sides of the triangle.
Using the diagram above, the midpoints of triangle ANT are AU, NG, and TB. The three midpoints intersect or are equal at point M. Point M is the centroid of triangle ANT.
Now, the height of a triangle is the segment that is also taken from the vertex of the triangle. But this section is perpendicular to the other side. Furthermore, every triangle also has three lengths and its common point is called the orthocenter of the triangle.
How To Find Orthocenter Of A Triangle
What is the most important thing about height and orthocenter? They allow us to quickly find the angles in a triangle.
Also, there are very interesting facts about the centroid and orthocenter of a triangle in which they correspond to the centroid of a circumscribed and circumscribed triangle!
Looking at the figure above, the lengths AD, BE and CF intersect or are equal at point O. Point O is the orthocenter of triangle ABC.
In the video below, we will see the different problems of finding the missing lengths and angles given media and height.

It will also recognize the coordinates of the center, given three vertices, and learn to distinguish between bisectors (the center of a circle), bisectors (inscribed centers), medians (centroids), and heights (orthocenter).
