It is called an arm of the angle.
The parts are arm vertex and ore
To measure an acute or obtuse angle:Put the cross-hairs at the centre of the base line of the protractor on the point of the angle;Align one zero on one arm of the angle (keeping the cross-hairs in place) with the circular part of the protractor over the other arm;Read off the angle of the other arm with the scale that starts at 0o on the first arm.To measure a reflex angle:Measure the angle (of the small angle) between the arms as above;Subtract the found angle from 360o.Note:The base line of the protractor is the straight line marked on the protractor that runs from 0o to 180o; half way along this line will be a perpendicular line towards the 90o mark which may touch or cross the base line - this point is the "cross-hairs".To draw a given angle:To draw an acute or obtuse angle:Draw one arm of the angle;Put the cross-hairs at the centre of the base line of the protractor on the end of the arm that forms the point of the angle;Align one zero on the drawn arm of the angle (keeping the cross-hairs in place) with the circular part of the protractor where the other arm should go;Mark the angle of the other arm with the scale that starts at 0o on the first arm.Draw in the other arm;Optional: mark the angle (between the lines) with a small arc near the point.To draw a reflex angle:Subtract the angle from 360oDraw as above; except the angle is marked with a small arc round the outside of the arms (instead of between them).
a ray in maths is a arm of an angle.
Only a very small force if the arm only has to be supported. What other weights do the arm carry and at what angle does the biceps attach to the fore-arm? What is the distance to the hand from the fulcrum and what is the arm weight (assuming a weight is in the hand and arm weight has to be added to the weight-in-hand)? The length of the hand to fulcrum is also required. There is no such thing as 90% angle: 90 degrees perhaps?
The arm is usually positioned at a 45 degree angle.
It is called an arm of the angle.
Flexion causes the angle of the elbow to decrease because you are moving your forearm closer to your bisep therefore the angle decreses. Extension is making the angle bigger for example, straightening you arm, you are extending your arm so that is where the term comes from
360 degrees

Well, honey, a reflex angle is anything greater than 180 degrees, so if you draw one arm at a reflex angle, the other arm will have to be straight to connect the two ends. So technically, yes, it is possible to draw a reflex angle where the other angle formed by the arm is straight. But seriously, why are we even talking about this? Just grab a protractor and have fun drawing some funky angles!
Yes
The Peerless Articulating Wall Arm will angle up to 180 degrees.

The needle should form a 15 to 30 degree angle with the surface of the arm.
Oh, what a lovely question! You see, when you draw a reflex angle, it always opens up more than 180 degrees. So, the other angle formed by the arm will always be acute, which means it will be less than 90 degrees. Just remember, every angle has a story to tell on your canvas of mathematics.
