∙ 15y agoAn 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.
They are called perpendicular.
An angle greater than 90 degree is an obtuse angle.
A right angle
complete angle

if the two line intersect at 90 degree then these are called perpendicular lines
