What is the if-then form for perpendicular lines intersect at right angles?
If two lines intersect at right angles then they are perpendicular!
Where does perpendicular lines intersect?
Perpendicular lines intersect at right angles to each other.
Perpendicular lines intersect each other to form what?
Perpendicular lines intersect to form right angles.
What has lines that intersect at right angles?
Perpendicular lines
If two lines intersect to form congruent adjacent angles will the lines be perpendicular?
Yes
If two lines intersect to form adjacent congruent angles then the lines are?
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.
Is it always true If two lines intersect to form congruent adjacent angles then the lines are perpendicular?
yes
What is the if-then form for perpendicular lines intersect at right angles?
If two lines intersect at right angles then they are perpendicular!
Where does perpendicular lines intersect?
Perpendicular lines intersect at right angles to each other.
Does a perpendicular lines intersect from right angles?
Perpendicular lines intersect to form right (90 degree) angles every time.
Perpendicular lines intersect each other to form what?
Perpendicular lines intersect to form right angles.
What has lines that intersect at right angles?
Perpendicular lines
What lines are intersecting lines that form right angles when they intersect?
Perpendicular lines form right angles when they intersect.
Lines that intersect to form right angles are called?
Perpendicular lines intersect to form right angles
What are lines that intersect right angles called?
Lines that intersect right angles (ninety-degree angles) are described as perpendicular.
What is the contra positive of this statement of two lines intersect to form right angles then they are 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."
