Perpendicular lines or parallel lines are two examples
A perpendicular line is formed when two lines meet at a right angle. Opposite angles in a perpendicular line are parallel to each other.
Right angles are formed by perpendicular lines. If the lines would extend, to make two intersecting lines, they would form four right angles. Perpendicular lines are written like this: . From its shape, you can already tell that it forms at least two right angles.
90 degrees.
They're supplementary
When two perpendicular lines cross, a right angle is formed.
No. Perpendicular lines for right angles. That is why they are called perpendicular.
90* angles
The definition of perpendicular lines also defines the angles -- perpendicular lines are two lines (or line segments) that meet at a 90 degree angle.
An angle is formed by the intersection of two straight lines. If the lines are perpendicular, they will form right angles.
Yes, that is the definition of perpendicular.
90 degree angles.
It doesn't have to be, but it can.
vertical line
Perpendicular lines or parallel lines are two examples
When two perpendicular lines cross you get four equal angles of 90 degrees.
When two lines intercept equal opposite vertical angles are formed and if the lines are perpendicular then right angles are formed
