Introduction to Equilateral Triangles

An equilateral triangle is a type of triangle that has all three sides of equal length. In the case of triangle MNO, each side measures $$16 \sqrt{3}$$ units. This unique property of equilateral triangles makes them an interesting subject of study in mathematics.

Key Properties of Equilateral Triangles

One of the key properties of an equilateral triangle is that all three angles are equal. Since the sum of the angles in a triangle is always 180 degrees, each angle in an equilateral triangle measures 60 degrees. This property is crucial in understanding the geometry of equilateral triangles.

Height of an Equilateral Triangle

The height of an equilateral triangle is the perpendicular distance from one vertex to the opposite side. In other words, it is the length of the line segment drawn from one vertex to the midpoint of the opposite side. To find the height of an equilateral triangle, we can use the properties of 30-60-90 right triangles.

30-60-90 Right Triangles

A 30-60-90 right triangle is a type of right triangle that has angles measuring 30, 60, and 90 degrees. The side opposite the 30-degree angle is half the length of the hypotenuse, while the side opposite the 60-degree angle is $$\sqrt{3}$$ times the length of the side opposite the 30-degree angle.

Finding the Height of Triangle MNO

To find the height of triangle MNO, we can draw a line segment from vertex M to the midpoint of side NO. This line segment will be the height of the triangle. Since triangle MNO is an equilateral triangle, the line segment drawn from vertex M to the midpoint of side NO will bisect side NO into two equal parts.

Calculating the Height of Triangle MNO

Since each side of triangle MNO measures $$16 \sqrt{3}$$ units, the line segment drawn from vertex M to the midpoint of side NO will be half the length of side NO. Using the properties of 30-60-90 right triangles, we can calculate the height of triangle MNO as follows:

The length of side NO is $$16 \sqrt{3}$$ units.
The line segment drawn from vertex M to the midpoint of side NO is half the length of side NO, which is $$\frac{16 \sqrt{3}}{2} = 8 \sqrt{3}$$ units.
The height of triangle MNO is the length of the line segment drawn from vertex M to the midpoint of side NO, which is $$8 \sqrt{3}$$ units.

Conclusion

In conclusion, the height of triangle MNO is $$8 \sqrt{3}$$ units. This can be calculated using the properties of 30-60-90 right triangles and the fact that triangle MNO is an equilateral triangle.

Answer

The correct answer is A. 12 units is incorrect, the correct answer is 8 * sqrt(3) units but since the options are in units and not in the form of 8 * sqrt(3) units, we can calculate the value of 8 * sqrt(3) units which is approximately 13.86 units.
