What is the measure of each angle in an equilateral triangle?

• A. 90 degrees
• B. 60 degrees
• C. 120 degrees
• D. 45 degrees

Answer: (C)

In an equilateral triangle, all three sides are of equal length, and as a result, all three angles are also equal. The sum of the angles in any triangle is always 180 degrees. Since an equilateral triangle has three equal angles, you can find the measure of each angle by dividing the total sum of the angles by three. So, you would calculate it as follows: 180 degrees divided by 3 equals 60 degrees. Therefore, each angle in an equilateral triangle measures 60 degrees. This property of equilateral triangles is fundamental in geometry and is essential for understanding the relationships between angles and sides in polygonal shapes.
