# How to find altitude of a triangle with coordinates

## How to Find the Altitude of a Triangle To find the equation of the altitude of a triangle, we examine the following example: Consider the triangle having vertices A(?3,2), B(5,4) and C(3,?8).

You use the definition of altitude in some triangle proofs. Imagine that you have a cardboard triangle standing straight up on a table. The above figure shows you an example of an altitude. Every triangle has three altitudes, one for each side. The following figure shows the same triangle from the above figure standing up on a table in the other two possible positions: with segment CB as the base and with segment BA as the base.

Go there now. This is a question some GMAT test takers ask. They know they would need the height to find the area, so they worry: how would I find that height. The short answer is: fuhgeddaboudit! Any triangle has three altitudes, and therefore has three heights.

Classifying Triangles What is Altitude? How to Find the Altitude? Triangles have a lot of parts, including altitudes, or heights. Learn how to find all the altitudes of all the different types of triangles, and solve for altitudes of some triangles. To find the altitude, we first need to know what kind of triangle we are dealing with. A triangle gets its name from its three interior angles. You can classify triangles either by their sides or their angles.

How to find the altitude of a triangle with coordinates :. Since the sides BC and AD are perpendicular to each other, the product of their slopes will be equal to Let us look into some example problems based on the above concept. Question 1 :. Solution :. After having gone through the stuff given on " How to find the altitude of a triangle with coordinates ", we hope that the students would have understood how to solve problems using unit rates. Apart from the stuff given on " How to find slope of altitude of a triangle ", if you need any other stuff in math, please use our google custom search here.

## Finding the Altitude of a Triangle

Video Definition Theorem Converse Examples. The orthocenter of a triangle is not something that comes up in casual conversation. Dealing with orthocenters, be on high alert, since we're dealing with coordinate graphing, algebra, and geometry, all tied together. It is anything but casual mathematics. A triangle , the simplest polygon with only three line segments forming its sides, have several interesting parts:. The orthocenter of a triangle is the intersection of any two of three altitudes the third altitude must intersect at the same spot. You can find the intersection of two altitudes using these four steps:.
