What are lines that form acute or obtuse angles at point of intersection?
RAYS
How many lines are there in an angle?
Two lines but they can't be parallel. It would be better to say two rays that share the same endpoint form an angle. However, two intersecting lines form angles also. Two rays can form a 180 degree angle if they share the same endpoint and point in exactly the opposite directions. Two perpendicular lines can form a right or 90 degree angle.
What refers to one of the rays that form an angle?
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.
Can parallel ray's form an angle?
No and yes. No, because parallel rays (if they don't share a common vertex) will never intersect and will never form any angles. Yes, because if they do have a common vertex, they would form a straight angle of 180°.
Are rays that are subsets of parallel lines may not be parallel?
chico
Angles across from each other that are always equal?
Vertical angles. These are two angles who, together, form two pairs of opposite rays. This means that these two angles form two lines that intersect. These angles have to be equal.
Can rays ever be parallel lines?
Rays aren't really lines, since (Euclidean) lines extend infinitely in all directions, so they can't be parallel lines. But that's to fret a bit too much over the wording. Yes, rays, just like lines and line segments, can be parallel to other rays, lines, or line segments.
How can two rays be parallel to each other?
If the slope of the lines are the same, it show that the lines are parallel.
Can parallel rays form angle?
Yes it can. Actually in non-euclidian geometry its possible that two parallel lines may form a angle, but it can never be possible in convention euclidian geometry (in which some of angles of a triangle is always 180 degrees, etc., such things are not sure in non-euclidian geometry).
What are lines that form acute or obtuse angles from the point of intersection?
Any pair or rays which are not mutually perpendicular.
What are lines rays and segments that form four right angles called?
They could be the four sides of a square.
Why can rays be perpendicular but not parallel?
Rays pass through one point. Parallel lines never meet.
