Can a reflex angle be 170 degrees?
A reflex angle is an angle that is more than 180° and less than 360°. b.) 170° is a reflex angle.
Is 180 reflex or obtuse?
A right angle is always 90 degrees. An obtuse angle is always between 90 degrees and 180 degrees. A straight angle is always 180 degrees (a straight line). A reflex angle is between 180 and 360.
Is a reflex angle considered obtuse?
Obtuse Angle – An angle more than 90 degrees and less than 180 degrees. Straight Angle – An angle that is exactly 180 degrees….Summary.
| Angle Type | Angle measure |
|---|---|
| Obtuse angle | Greater than 90°, less than 180° |
| Straight angle | 180° |
| Reflex angle | Greater than 180°, less than 360° |
What is a reflex obtuse?
An obtuse angle is one that measures between 90˚ and 180˚. A reflex angle is an angle that measures between 180˚ and 360˚.
What is a 170 degree angle called?
An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170°, etc. ∠ PQR is an obtuse angle because it’s less than 180° and greater than 90°.
What angle is 170 degrees?
| Number of degrees | Type of angle | Reason |
|---|---|---|
| 170 | Obtuse | > (greater than) 90 degrees |
| 90 | Right angle | = 90 degrees |
| 270 | Reflex | >(greater than) 180 degrees |
| 45 | Acute | < (less than) 90 degrees |
What angles are acute?
Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
What is a acute obtuse and reflex angle?
An angle less than 90° is acute. An angle between 90° and 180° is obtuse. An angle greater than 180° is reflex. An angle of exactly 90° is a right-angle.
What is acute right and obtuse angles?
Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees. Learn about angles types and see examples of each.
