Properties of Equilateral Triangles

The video tutorial from MooMooMath explains equilateral triangles, focusing on their properties. It begins by identifying equilateral triangles through congruent sides and symbols. The tutorial then discusses angle measures, explaining that each angle in an equilateral triangle is 60 degrees, as the sum of angles in any triangle is 180 degrees. Finally, it summarizes the rules: all sides and angles in an equilateral triangle are congruent, with angles always measuring 60 degrees.

What is one way to identify an equilateral triangle?

• All angles are 90 degrees.

• All sides are marked congruent.

• It has one right angle.

• It has two equal sides.

How do you calculate the measure of each angle in an equilateral triangle?

• Add 60 to 60.

• Divide 180 by 3.

• Multiply 60 by 3.

• Divide 180 by 2.

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

• 45 degrees

• 60 degrees

• 90 degrees

• 120 degrees

Which of the following is true for an equilateral triangle?

• It has two equal angles.

• All sides and angles are congruent.

• It has one angle greater than 90 degrees.

• It has two sides of different lengths.

What is the total sum of the angles in any triangle?

• 90 degrees

• 360 degrees

• 180 degrees

• 270 degrees
