How to Calculate the Altitude of a Triangle: Step-by-Step Guide

altitude of a triangle Chapter 6 (p. 311)

The altitude of a triangle is a line segment that is perpendicular to the base of the triangle and extends from the vertex opposite the base to the base itself

The altitude of a triangle is a line segment that is perpendicular to the base of the triangle and extends from the vertex opposite the base to the base itself.

To find the altitude of a triangle, you can use the formula:

Altitude = (2 * Area of the triangle) / Base

Here’s how you can calculate the altitude of a triangle step by step:

1. Determine the length of the base of the triangle.
This could be given in the problem statement or can be measured if you have the triangle.

2. Calculate the area of the triangle.
You can use different methods to find the area, such as using the base and height, or using Heron’s formula if you have the lengths of all three sides. Let’s assume you have already calculated the area.

3. Plug in the values into the formula.
Substitute the values of the area and the base length into the formula for the altitude.

4. Simplify and compute.
Multiply the area by 2, and divide the result by the base length. This will give you the altitude of the triangle.

5. Write down your answer and include the appropriate units.
Make sure to provide the answer in the correct units, such as centimeters, inches, or any other applicable unit of measurement.

Remember, it’s important to double-check your calculations and units to ensure accuracy.
