If the side length of an equilateral triangle is 5 centimeters, the length of altitude is about 4.33 centimeters.
What is an equilateral triangle?
An equilateral triangle can be defined as a type of triangle or regular polygon that has equal side lengths and all of its interior angles are equal.
How to calculate the length of altitude.
Mathematically, the length of altitude of an equilateral triangle is calculated by using this formula:
[tex]L=\frac{\sqrt{3} }{2} a[/tex]
Where:
- L is the length of altitude.
Given the following data:
- Side length = 5 centimeters.
Substituting the given parameters into the formula, we have;
[tex]L=\frac{\sqrt{3} }{2} \times 5\\\\L=\frac{5\sqrt{3} }{2}[/tex]
Length = 4.33 centimeters.
