Answer:
Acute angles are those with a measure of less than 90° (the right angle). And obtuse angles are defined as angles with a measure greater than 90° (right angle).
Step-by-step explanation:
- Acute angles range from 0° to 90°.
- More than 90° but less than 180° is considered an obtuse angle.
- A right angle is 90 degrees.
- Angle of a straight line is 180°.
Less than 90 degrees is the acute angle measurement. Right angles are 90 degrees in length. Angles that are obtuse are more than 90 degrees.
1. Acute Angle:
An acute angle is one that is less than 90° in length. the 0 to 90 degree angle range. In the illustration below, the angle PQR, which is 45°, is created when PQ and QR cross at Q. PQR is hence referred to as an acute angle.
2. Right Angle:
Right angles are angles that are exactly 90 degrees in length. It typically results from the intersection of two perpendicular lines. In the illustration below, line AB crosses line BC at B, creating the 90° angle ABC.
3. Obtuse Angle:
A greater angle than 90° is referred to as having a "obtuse angle." Angle measurements can be made between 90° and 180°. If we know the acute angle's measurement, we may also determine the obtuse angle.
4. Straight Angle:
Straight angles are angles that are exactly 180 degrees in length. The term "straight angle" refers to how this resembles a straight line. Obtuse and acute angles on a line are combined to form a straight angle.
5. Reflex Angle:
The reflex angle is that angle that is larger than 180 degrees and less than 360 degrees. Since the reflex angle is complementary to the acute angle on the other side of the line, it can be determined if the acute angle's measurement is known.
