Only if the angles formed are right angles otherwise they form vertical opposite equal angles
yes
If two lines intersect at right angles then they are perpendicular!
Perpendicular lines intersect at right angles to each other.
Perpendicular lines intersect to form right angles.
Perpendicular lines
Yes
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
yes
If two lines intersect at right angles then they are perpendicular!
Perpendicular lines intersect at right angles to each other.
Perpendicular lines intersect to form right (90 degree) angles every time.
Perpendicular lines intersect to form right angles.
Perpendicular lines
Perpendicular lines form right angles when they intersect.
Perpendicular lines intersect to form right angles
Lines that intersect right angles (ninety-degree angles) are described as perpendicular.
The contrapositive to the statement, "if two lines intersect to form right angles, then they are perpendicular," is "if two lines are not perpendicular, then they do not form right angles."
