CCSS What is the Angle Addition Postulate

The video explains the angle addition postulate, which states that the sum of two angles equals the larger angle they form. It uses examples of straight angles and general angles to illustrate this concept, emphasizing that the total measure remains unchanged when an angle is divided into smaller parts.

What does the angle addition postulate state about the sum of two angles?

• The sum is always less than the larger angle.

• The sum is equal to the larger angle they form.

• The sum is always more than 180 degrees.

• The sum is always 90 degrees.

If a straight angle is divided into two parts, what is the sum of these two angles?

• 90 degrees

• 180 degrees

• 360 degrees

• 45 degrees

How does the angle addition postulate apply to a straight angle?

• It states that the sum of the divided angles is always 90 degrees.

• It states that the sum of the divided angles is always 180 degrees.

• It does not apply to straight angles.

• It only applies if the angle is less than 90 degrees.

What happens to the measure of a larger angle when it is divided into smaller angles?

• The measure of the larger angle becomes zero.

• The measure of the larger angle increases.

• The measure of the larger angle remains the same.

• The measure of the larger angle decreases.

According to the angle addition postulate, what is true about the sum of smaller angles formed by dividing a larger angle?

• The sum is less than the measure of the larger angle.

• The sum is always 90 degrees.

• The sum is equal to the measure of the larger angle.

• The sum is more than the measure of the larger angle.
