A simple way to test that X lies between A and B isIf (A-X)*(B-X) is negative then X lies between them.If (A-X)*(B-X) is positive then X does not lie between them.If (A-X)*(B-X) is zero then X = A or X = B.There are many methods.

Acute: 0 < X < 90; Right: = 90; Obtuse: 90 < X < 180; Straight: = 180; Reflex: 180 < X < 360. The Acut, Right, Straight and Reflex are actually classifications of an angle. Naming of an angle is done by identifying the vertex and a combination of the vertex and points on the two rays. For example an angle with points ABC where B is the vertex and A and C are points on the accompanying rays may be named as angle B, angle ABC or angle CBA. These can be written with the symbol for angle placed before the B the ABC and the CBA.

Revolving with precision, this angle bends, Ensuring a turn that never ends. Lateral thoughts on its way, Exemplifying its sway. X marks the spot where it lays.
Extending a line past a side of the polygon, and measuring the angle between the adjacent side and the line. This angle will equal 180°-(interior angle). Below, I've tried to illustrate it, where x is the exterior angle, and i is the interior angle: x\ i __\_______/
Term What angle is between 90 and 180 Definition 1/20 An angle that is between 90 degrees and 180 degrees is called an obtuse angle. Ex. : 175 degrees, 140 degrees
<ab> = |a|*|b|*cos(x) where |a| is the length of the vector a, |b| is the length of the vector b, and x is the angle between them.
Call the angle from the incident ray to the normal X. The angle of the reflected ray to the normal also has to be X because the incidence angle and the reflected angle are equal by law of reflection. Since the angle between the reflected and incident ray is 90 degrees: 2*X = 90 So, X = 45 degrees.
By the looks of it, x + 7 is a vector of degree one polynomials. An angle are between vectors, not only one. Hence there is no angle. You might as well say 0 since that's the angle with itself.
Example: Express sin 120⁰ as a function of an acute angle (an angle between 0⁰ and 90⁰).Solution:Each angle θ whose terminal side lies in quadrant II, III, or IV has associated with it an angle called the reference angle, alpha (alpha is formed by the x-axis and the terminal side).Since 120⁰ lies on the second quadrant, then alpha = 180⁰ - 120⁰ = 60⁰.Since sine is positive in the second quadrant, sin 120⁰ = sin 60⁰.Example: Express tan 320⁰ as a function of an acute angle.Solution:Since 320⁰ lies on the fourth quadrant, then alpha = 360⁰ - 320⁰ = 40⁰.Since tangent is negative in the fourth quadrant, tan 320⁰ = -tan 40⁰.
