What is a horizontal angle?
A horizontal angle is an angle between lines on a horizontal plane.
Two segments in the same plane are parallel if the containing them are parallel is called?
Lines
What are lines in the same plane that are not parallel and do not intersect?
If they are not parallel and do not intersect then they would not be in the same plane (not possible), but they would be called skew lines.
Are two lines from the same plane parrellel?
They can be, but not necessarily. If two lines in the same plane never intersect, they are parallel. Though, two lines can exist in the same plane without being parallel. Ie, two lines that intersect at a 90 degree angle are perpendicular. Most lines in a plane aren't parallel.
What are lines that are not on the same plane do not intersect and are not parallel called?
They are called skew lines.
Why are they called unparalleled bars when they are parallel in the same plane.?
It is because they are not in a plane that is parallel to the horizontal.
A shape with no right angle with a reflex angle four sides two parallel sides and have the same lenght?
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
What is a horizontal angle?
A horizontal angle is an angle between lines on a horizontal plane.
What is increasing the angle between two bones called?
Increasing the angle between two bones is called extension. This movement typically occurs in the sagittal plane and usually straightens or lengthens the joint.
Two segments in the same plane are parallel if the containing them are parallel is called?
Lines
Does a plane mirror converge a parallel beam of light?
No. The angle of incidence will equal the angle of reflection. No convergence will take place.
What is parallel lines properties?
They have the same angle relative to any plane or line and never intersect.
What are lines in the same plane that are not parallel and do not intersect?
If they are not parallel and do not intersect then they would not be in the same plane (not possible), but they would be called skew lines.

Why are plane waves are called plane?
Plane waves travel parallel to each other in the same plane hence the name.
Is it true that frictional force on a sliding body on a plane is always directed at the angle of friction to the normal?
The frictional force on a sliding body on a plane will be acting parallel to the plane against the motion of the body. But the magnitude of the (kinetic) friction force is proportional to the weight component normal to the plane. The weight component parallel to the plane is the force that tends to slide the body down the inclined plane. When the sliding body has acquire steady velocity, the friction force is equal to the body's sliding force.
What are lines that are not on the same plane do not intersect and are not parallel called?
They are called skew lines.
