∙ 12y agoA horizontal angle is an angle between lines on a horizontal plane.
Lines
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.
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.
They are called skew lines.
It is because they are not in a plane that is parallel to the horizontal.
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
No, a plane mirror does not converge a parallel beam of light. It reflects light rays without changing their direction, so the reflected beam remains parallel to the incident beam.
A horizontal angle is an angle between lines on a horizontal plane.
Increasing the angle between two bones is called extension. This movement typically occurs in the sagittal plane and usually straightens or lengthens the joint.
They have the same angle relative to any plane or line and never intersect.

No, the frictional force on a sliding body on a plane is always directed parallel to the surface of contact, opposite to the direction of motion. The angle between the frictional force and the normal force depends on the surface materials and conditions but is not always at the angle of friction to the normal.
Plane waves travel parallel to each other in the same plane hence the name.
I'm assuming you are looking for the name of the conic section produced by this type of intersection? If a right circular cone is intersected by a plane parallel to one edge of the cone, the resulting curve of intersection would be a parabola. If the intersecting plane was parallel to the base, it would be a circle. If the intersecting plane was at any angle between being parallel to the base and being parallel to an edge, it would produce an ellipse or part of an ellipse (depending on whether the intersection was completely within the cone).
