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.
What is formed by perpendicular lines?
Perpendicular lines formed right angles.
True or false Perpendicular lines form straight angles?
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
What angles do perpendicular lines form?
right angles
What shape has parallel lines perpendicular lines equal opposite angles and equal adjacent angles?
square
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.
If two intersecting lines form congruent adjacent angles then the lines are perpendicular?
Yes.
Is it always true If two lines intersect to form congruent adjacent angles then the lines are perpendicular?
yes
If two lines are intersected by a transversal so that the alternate exterior angles are congruent, then the lines are perpendicular.?
false
If two lines intersect to form adjacent angles then the lines are perpendicular?
Only if the angles formed are right angles otherwise they form vertical opposite equal angles
Is this statement true or falseIf two lines are intersected by a transversal so that the alternate exterior angles are congruent, then the lines are perpendicular.?
false
ARE Acute angles are formed by perpendicular lines?
No. Perpendicular lines for right angles. That is why they are called perpendicular.
What is a rectangle's perpendicular lines?
A rectangle's perpendicular lines are ALWAYS adjacent to eachother
What is the if-then form for perpendicular lines intersect at right angles?
If two lines intersect at right angles then they are perpendicular!
What is formed by perpendicular lines?
Perpendicular lines formed right angles.
