Perpendicular lines.
When two lines meet to form an angle the lines are intersecting.
They are perpendicular lines that meet to form right angles
"right angle" is two lines that intersect at 90 degrees "acute angle" is when 2 lines meet at less than 90 degrees "obtuse angle" is when lines meet at an angle more than 90 degrees , a straight angle is when 2 lines meet at exactly 180 degrees.
Perpendicular lines are lines that meet to form a right angle.
It is important to know terminology when learning math. The Vertex is the point where two lines meet and form and angle.
lines that meet to form a right angle are called? I believe this line is known as a perpendicular line :)
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.
it means that two lines meet and form a right angle.
no since they won't ever meet.
That's the "vertex" of the angle.
They are called perpendicular.
A polygon with four or more sides can meet all of the requirements.
