what is a Reflex Angle?

Answer 1

Angles larger than two right angles are called reflex angles (more than 180 degrees).

Answer 2

180

Answer 3

Angle which measures more than 180 but less than 360 are refered as reflex angles.

Answer 4

Angles larger than two right angles are called reflex angles (more than 180 degrees).


It depends a little on the area you work in. After plane geometry, it
is usually defined as an angle between 180 and 360 degrees. In plane
geometry it is often defined as an angle that makes a polygon concave:
think of one that bends into a polygon and not out.

I will try to make an ASCII drawing showing the angle at vertex A as
the reflex angle:

where as an angle is
An angle greater than 180° and less than 360°.

A full angle is therefore a reflex angle, while acute, obtuse, right, and straight angles are not.
An angle is the figure formed by two rays sharing a common endpoint, called the vertex of the angle. Angles provide a means of expressing the difference in slope between two rays meeting at a vertex without the need to explicitly define the slopes of the two rays. Angles are studied in geometry and trigonometry.

Euclid defines a plane angle as the inclination to each other, in a plane, of two lines which meet each other, and do not lie straight with respect to each other. According to Proclus an angle must be either a quality or a quantity, or a relationship. The first concept was used by Eudemus, who regarded an angle as a deviation from a straight line; the second by Carpus of Antioch, who regarded it as the interval or space between the intersecting lines; Euclid adopted the third concept, although his definitions of right, acute, and obtuse angles are certainly quantitative.

The word angle comes from the Latin word angulus, meaning "a corner". The word angulus is a diminutive, of which the primitive form, angus, does not occur in Latin. Cognate are the Latin angere, meaning "to compress into a bend" or "to strangle", and the Greek ἀγκύλος (angulοs), meaning "crooked, curved"; both are connected with the PIE root *ank-[1], meaning "to bend".

Answer 5

A reflex angle is an angle with a measure that is larger than 180 degrees but lower than 360 degrees.

Answer 6

A reflex angle is an angle that measures greater than 180 degrees, but less than 360 degrees.

Answer 7

A reflex angle is an angle of more than 180 degrees.

A full angle is therefore a reflex angle, while acute, obtuse, right, and straight angles are not.

A reflex angle is greater than 180º and less than 360º.

Answer 8

A reflex angle is an angle of more than 180 degrees.

A full angle is therefore a reflex angle, while acute, obtuse, right, and straight angles are not.

Answer 9

a reflex angle is an angle that is more than 180 degrees but less than 360 degrees.

Answer 10

if the angle measure is between 180*and 360* it is called a reflex angle
