Another measurement could be 283-360 or -77* or 283+360 or 643*
Congruent angles have the same measure. congruent Kenpachi54 improve answer: Actually, angles don't have to be congruent just to have the same angle measurements A has a right angle is 90 degrees. even if there is a small right angle and a large right angle you know they are both 90 degrees because ALL right angles are 90 degrees, so there is really no name for it.
To have a congruent angle, the measure of the two angle must be the same, so if ABC is 15 degrees, then FDE would have to be 15 degrees also to be congruent.
No, because a complamentary angle just equals 90 degrees. An adjacent angle has a vertex and a common ray the same. If you have two angles that are not touching they cannot be adjacent because they dont have a same ray, but they may have a same vertex. If the two angles add up to 90 degrees they are complimentary and dont have to have anything the same. Hope this helps! If it is confusing look up what an adjacent angle is, then look up what a complamentary angle is! :)
Get some graph paper, draw two axes and bisect them with a 45 degree sloping line. Next pick any point on that 45 degree sloping line and from that point draw a line parallel to the horizontal axis so that it intersects the vertical axis. Do the same thing from the point drawing a line parallel with the vertical axis so that it intersects the horizontal axis. These two lines represent represent the components of your vector and if you measure them they will be of equal length and thus of equal magnitude. For ANY angle of slope (other than 45 degrees) the two vectors will not be of equal length.
