# Angle FAQs:

Q: Is an angle the figure formed by two rays?

A: Yes, and called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

Q: Is an angle 100 grads?

A: Yes.

Q: Are angles angle pairs whose measures sum to one right angle?

A: Yes, If the two complementary angles are adjacent their non-shared sides form a right angle.

Q: Is an angle termed the explement of the angle or conjugate of an angle?

A: Yes.

Q: Is an angle an argument of a hyperbolic function just as the circular angle is the argument of a circular function?

A: Yes.

Q: Is an angle 1/24 of a turn?

A: Yes.

Q: Are angles called the vertical angle theorem?

A: Yes.

Q: Is an angle the same?

A: Yes, and any angle of rotation that maps one of the lines into the other leads to the same value for the spread between the lines.

Q: Is an angle supplementary to the third?

A: Yes, because the sum of internal angles of a triangle is a straight angle.

Q: Is an angle a reflex angle?

A: Yes, and the exterior angle should be considered negative.

Q: Are angles considered as dimensionless?

A: Yes.

Q: Are angles called a linear pair of angles?

A: Yes.

Q: Is an angle drawn, e.g?

A: Yes, with a pair of compasses.

Q: Is an angle usually characterized by the magnitude of the smallest rotation that maps one of the rays into the other?

A: Yes.

Q: Is an angle termed the complement of the angle?

A: Yes.

Q: Are angles also formed by the intersection of two planes in Euclidean and other spaces?

A: Yes.

Q: Are angles formed?

A: Yes.

A: Yes, and their non-shared sides form a straight line.

Q: Is a angle also used to designate the measure of an angle or of a rotation?

A: Yes.

Q: Is an angle typically defined by its two sides?

A: Yes, and with its vertex at the origin.

Q: Is an angle said to be normal?

A: Yes, and orthogonal, or perpendicular.

Q: Are angles equal?

A: Yes.

Q: Are angles listed below in descending magnitude order?

A: Yes.

Q: Are angles named according to their location relative to each other?

A: Yes.

Q: Are angles commonly used in Logo Turtle Geometry when drawing regular polygons?

A: Yes.

Q: Is an angle the acute version of any angle determined by repeatedly subtracting or adding straight angle?

A: Yes, and to the results as necessary, until the magnitude of result is an acute angle, a value between 0 and 1/4 turn, 90°, or π/2 radians.

Q: Is an angle unbounded?

A: Yes.

Q: Are angles supplementary to both of the adjacent angles?

A: Yes, and the vertical angles are equal in measure.

Q: Is an angle called an exterior angle?

A: Yes, that is, an interior angle and an exterior angle form a linear pair of angles.

Q: Is an angle measured determines its sign?

A: Yes, However, in many geometrical situations it is obvious from context that the positive angle less than or equal to 180 degrees is meant, and no ambiguity arises.

Q: Is an angle measured as long as each angle is measured in the same unit?

A: Yes.

Q: Are angles equal if one accepted some general notions such as: all straight angles are equal?

A: Yes, and equals added to equals are equal, and equals subtracted from equals are equal.

Q: Are angles positive clockwise?

A: Yes, so a bearing of 45° corresponds to a north-east orientation.

Q: Is an angle called oblique angles?

A: Yes.

Q: Is an angle "filled up" by its complement to form a right angle?

A: Yes.

Q: Are angles vertical angles and hence are equal?

A: Yes.

Q: Is an angle complementary?

A: Yes, because the sum of internal angles of a triangle is 180 degrees, and the right angle itself accounts for ninety degrees.

Q: Are angles certainly quantitative?

A: Yes.
