Best Answer

If you know the gradient for a line (the m in y = mx + c) then tan-1 (m) will give you the angle between the line and the x axis.

So do tan-1 for both gradients and subtract to find angle between the lines.

An angle is formed where two lines meet. Parallel lines do not meet. Therefore they do not form an angle. So there is no angle to have a name. So no name.

An angle is formed by the intersection of two straight lines. If the lines are perpendicular, they will form right angles.

A 90 degree angle is formed at a right angle.

If you mean an angle then an angle is formed by two straight lines meeting at a vertex.

It could be an obtuse, right, or acute angle depending on how the lines connect.
