Between zero and 90 degrees.
There are 90 degrees in a left angle as there are in a right angle but the term 'left angle' is rarely used
Angles are units of measure that define the relationships between two intersecting lines It's tough to demonstrate by text, but I'm goind to give it a try; _\ = an angle of about 60 degrees _/ = an angle of about 120 degrees _| = an angle of 90 degrees (also called a 'right' angle) _._ = an angle of about 180 degrees = is an angle of about 0 degrees

A Mathematically Definition Would Be: If An Angle Is a Right Angle, Then It's Measure Is 90 Degrees. We Talked About This In Math Today :)
A theodolite is an instrument that is used in archaeoastronomy. To change the face for taking angle measurements when using a theodolite you must turn the telescope by 180 degrees.
An angle greater than 0 but less than 90 degrees
A degree is the measure of an angle.
Acute
The greek letter theta is usually used to denote an unknown angle. An angle of 90 degrees is a right angle, an angle between 0-90 degrees is an acute angle, bigger than 90 degrees but less than 180 is an obtuse angle, and bigger than 180 but less than 360 is a reflex angle.
The other two angles are "acute angles". The sum of the angles in a triangle MUST add up to 180 degrees. If 90 of the degrees are used up in the right angle (the very definition of a right angle), then that leave 90 degrees to be divided up between the two remaining angles. Thus, they would both be LESS THAN 90 degrees (the very definition of an acute angle.)
The term "acute" is used to describe something that is sudden, severe, or intense. It is often used in a medical context to refer to a condition or illness that has a rapid onset and a relatively short duration. Acute can also refer to the angle less than 90 degrees between two lines or surfaces.
The acute angle looked like a sharp spike.
If you think of two lines creating an angle of 30 degress. such as a slice of pie, the angle from the outside of one line around to the outside of the other line, or where the rest of the pie would be would be 330 degrees. If you understand that and are just lookin for the tern used for 330 degrees this is REFLEX. A reflex angle is from 180 degrees to 360 degrees. with angles <90degrees being ACUTE and angles >90 degrees <180 degrees called OBTUSE
Sine can be found in degrees by taking the length of the opposite side and hypoteneuse. Then divide the opposite side by the hypoteneuse. Any calculator can be used to find this. for example, if the hypoteneuse side was 7, and the opposite side was 3, and you labeled the angle "A", then it would be "sineA= 3/7" ...... then A=sin^-1 (3/7) and you put that in your calculator and the answer you get is the angle in degrees (if the calculator is in degrees mode, and if the angle is an acute angle).
Whatever they're used for, right angles cannot be acute.
Look at whether it is acute, obtuse or reflex. Then, look at the acute component of the angle and try to estimate whether it is half a right angle (45 deg), a third (30 deg) or two third (60 deg). If you are good, then you could try estimating "between a third and a half = 35-40 degrees".
Angles are measured in 4 categories and they are:- 1 Acute angle which is greater than 0 but less than 90 degrees 2 Right angle which is 90 degrees 3 Obtuse angle which is greater than 90 but less than 180 degrees 4 Reflex angle which is greater than 180 but less than 360 degrees A complete rotation is 360 degrees and angles are measured in degrees, minutes and seconds
