Perpendicular angles
perpendicular lines
Perpendicular lines intersect to form right (90 degree) angles every time.
Yes, all perpendicular angles form 90 degree angles.
Perpendicular lines.
no, it makes four 90 degree angles
Two lines that intersect and form 90-degree angles (right angles) are "perpendicular" to each other. You would call them "perpendicular lines."

Perpendicular :)
Lines are perpendicular when they form a 90-degree angle so if the angles of two lines don't add up to 90, they are not perpendicular.
By definition, perpendicular lines form right angles.
perpendicualr lines form 90 degree angles and intersecting lines just insersect. perpendicular: _ l _ intersecting: x l
