"A point is that which has no part" --Euclid
All points are identical -- they only have location (usually in the form of X/Y coordinates), no other properties.
Angles also have magnitude (how wide they are, in degrees or radians) and lines have slope. Rays have slope, as well as a single endpoint (they are "half of a line" so to speak). Line segments have two endpoints.
if the rays have no common points, the answer is zero. if the rays all have the same end point, the answer is 21 -- counting only the acute angles.
RAYS
Geometry teaches points, lines, rays, chords and segments.
Parallel lines--will never touch Perpendicular lines--cross at right angles Rays--lines that start at a point and extend into infinity Line segment--a line between two points Line--a line that runs forever in either direction
Plotting points. Graphing lines, line segments, rays, etc.
it dont have similarity
No.
A side refers to one of the rays that form an angle. Vertical are also called opposite angles. They are nonadjacent angles formed by intersecting lines.
If I understand the question: Either pair of opposite angles formed by the intersection of 2 lines.
Yes, the middle of the figure would make exactly four right angles if there were two lines (rays or line segments) in the figure. By:Donny Heitler
A right angle.
They could be the four sides of a square.
