# Is Obtuse the Largest Angle?

No, obtuse angles are not the largest angles. The angle with the greatest measure is a straight angle (180 degrees). An obtuse angle has an angle measure between 90 and 180 degrees. Acute angles have measures less than 90 degrees, while right angles are exactly 90 degrees. Therefore, an obtuse angle is neither the largest angle nor the smallest angle.

It is important to note that obtuse angles can be larger or smaller than other obtuse angles, depending on the measure of each angle. The measure of an angle is determined by how much it has “opened” from its original starting point. A 180-degree angle (straight line) is the largest possible angle, while a 0-degree angle (a point) is the smallest.

In summary, obtuse angles are not necessarily larger or smaller than other angles; they have an angle measure between 90 and 180 degrees. The largest angle is a straight line (180 degrees) and the smallest angle is a point (0 degrees).

## What is the biggest angle?

The biggest angle is a straight angle, which has an angle measure of 180 degrees. This is the largest possible angle and it forms a straight line when two rays meet at a common endpoint. Acute angles have measures less than 90 degrees while obtuse angles have measures between 90 and 180 degrees. Right angles are exactly 90 degrees in measure.

## What is the biggest acute angle?

The biggest acute angle has a measure of 90 degrees. This is also known as a right angle and forms an L-shape when two rays meet at a common endpoint. Acute angles have measures less than 90 degrees, obtuse angles have measures between 90 and 180 degrees, and straight angles are the largest angle with a measure of 180 degrees.

## What is the largest reflex angle?

The largest reflex angle has a measure of 360 degrees. This is also known as a complete angle and forms a closed loop when two rays meet at a common endpoint. Acute angles have measures less than 90 degrees, obtuse angles have measures between 90 and 180 degrees, and straight angles are the largest angle with a measure of 180 degrees. A reflex angle is larger than 180 degrees and has an angle measure between 180 and 360 degrees.

## What is the smallest angle?

The smallest angle has a measure of 0 degrees. This is also known as a point and forms a single endpoint when two rays meet at a common endpoint. Acute angles have measures less than 90 degrees, obtuse angles have measures between 90 and 180 degrees, and straight angles are the largest angle with a measure of 180 degrees. A reflex angle is larger than 180 degrees and has an angle measure between 180 and 360 degrees. Therefore, the smallest angle is 0 degrees (a point).
