Parallel lines form congruent alternate interior angles?
Parallel lines cut by a transversal form congruent alternate interior angles.
Do intersecting lines form four pairs of complementary angles?
No, intersecting lines form four pairs of supplementary angles
If two congruent angles form a supplementary they are acute angles.?
Not true because supplementary angles add up to 180 degrees and two acute angles would be less than 180 degrees.
Do intersecting lines form four pairs of supplementary angles?
Yes. If two intersecting lines form the angles A, B, C and D (in rotational order) then AB, BC, CD and DA are pairs of supplementary angles.
If two lines are cut by a transversal to form pairs of congruent corresponding angles congruent alternate interior angles or congruent alternate exterior angles then what are the lines?
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
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.
Do intersecting lines form two pairs of congruent angles?
yes, intersecting lines form two pairs of congruent angles
Parallel lines form congruent alternate interior angles?
Parallel lines cut by a transversal form congruent alternate interior angles.
Do intersecting lines form four pairs of complementary angles?
No, intersecting lines form four pairs of supplementary angles
What is the converse of parallel lines conjecture?
If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.
If two congruent angles form a supplementary they are acute angles.?
Not true because supplementary angles add up to 180 degrees and two acute angles would be less than 180 degrees.
What are two right angles?
They would be called "supplementary angles" because 90º + 90º = 180º and any two angles that add to 180º form straight, parallel, or congruent lines.(Angles that add to 90 º are called complementary.)
Do intersecting lines form four pairs of supplementary angles?
Yes. If two intersecting lines form the angles A, B, C and D (in rotational order) then AB, BC, CD and DA are pairs of supplementary angles.
If two angles are vertical angles then they are congruent?
yes they are because they meet to form at a right angle
If two lines intersect to form congruent adjacent angles will the lines be perpendicular?
Yes
If two lines are cut by a transversal to form pairs of congruent corresponding angles congruent alternate interior angles or congruent alternate exterior angles then what are the lines?
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
What is the linear pair postulate?
1. Where the angles in a linear pair are supplementry, and if parallel lines are cut by a transversal, then the interior angles are congruent, and if two lines are cut by a transversal so that a pair of alternate interior angles are congruent, then the two lines are parallel. That's what makes up a linear pair postulate anyway. 2. If two adjacent angle's unshared sides form a straight angle, then they are a linear pair. 3.If two angles form a linear pair,then they are supplementary.
