What Is an Altitude in Geometry? 

Altitude is a common geometric concept used to measure height. It is an important concept in geometry, and can be used to calculate missing measurements in triangles. Depending on the type of triangle, the altitude is located at different points. The altitude can be perpendicular to the base or extend from the base. Aside from being a measurement, altitude is also used to determine the orthocenter of a triangle.

The Pythagorean Theorem can be used to find the altitudes of a triangle. In a right triangle, the altitudes are called the legs. These legs are naturally perpendicular to the sides of the triangle. The two altitudes that form the legs of a right triangle are the hypotenuse and the vertex. As a result, the length of the altitudes in an equilateral triangle with a side of 2 cm is 2 cm. 

There are three basic types of triangles. They include the right triangle, the scalene triangle, and the isosceles triangle. Each of these has a formula that is used to determine the altitude. Using these formulas, you can find the altitudes of any type of triangle. Knowing the formulas for each of these triangles will help you understand the basics of geometry, and will help you develop a solid foundation for more advanced geometry concepts. 

An obtuse triangle, as well as a triangle with an obtuse angle, has an altitude that is outside the triangle. On the other hand, an acute triangle has an altitude inside the triangle. This altitude makes a right angle with the base of the triangle. To calculate the altitude of an obtuse triangle, you can use the following formula: (x+y+h) – e. However, the altitude of an obtuse or a triangle with an obtuse side is different from that of an isosceles or a triangle with an obtuse base. 

One of the most important altitudes in geometric figures is the one that divides the equilateral triangle into two right triangles. This altitude, referred to as AE, is the altitude that divides the base BC into the hypotenuse and the EC. 

Another important altitude is the shortest altitude. This is the altitude that is perpendicular to the shortest side of the triangle. Using the Pythagorean Theorem, you can determine the shortest altitude for any type of triangle. For example, the shortest altitude of an equilateral triangle with a 2cm side length is the one that is perpendicular to the smallest side of the triangle. 

An equilateral triangle with a base that is equal to all of the sides of the triangle is a right triangle. Similarly, a triangle with a side that is equal to all of the sides of a triangle is an isosceles triangle. Using the shortest altitude of an isosceles or an obtuse triangle, you could calculate the length of the obtuse side. 

Finally, there is the Heron’s formula. Using this formula, you can determine the area of a triangle. While it is not a complete mathematical formula, it does provide a useful way of calculating the area of a triangle. Generally, you will multiply the length of the base by the length of the altitude to get the area.
