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 lines intersect to form congruent adjacent angles will the lines be perpendicular?
Yes
How many pairs of adjacent angles are formed when two lines intersect?
Two pairs of adjacent angles are formed when two lines intersect each other.
Are all angles of a parallelogram congruent?
All angles of a parallelogram are not necessarily congruent. A parallelogram means that the opposite sides run in straight lines that don't intersect. An example is a rectangle or square. Length of sides DO NOT determine if opposite angles are congruent. As long as opposite sides do not intersect each other at any point (if you continue to draw the lines), then the angles diagonal from each other are the same.
What are non adjacent angles that are congruent and share a common vertex?
Where two straight lines cross the "vertically opposite" angles are equal.
Lines that intersect to form right angles are called?
Perpendicular lines intersect to form right angles
If two lines intersect to form congruent adjacent angles will the lines be perpendicular?
Yes
Is it always true If two lines intersect to form congruent adjacent angles then the lines are perpendicular?
yes
What are opposite angles that are formed when two lines intersect and are congruent called?
Perpendicular is when opposite angles that are formed when two lines intersect and are congruent called?
What is a vertical angle-?
Whenever two lines intersect, vertical angles refers to the angles opposite each other
How many pairs of adjacent angles are formed when two lines intersect?
Two pairs of adjacent angles are formed when two lines intersect each other.
How do you construct adjacent congruent angles?
Draw to lines intersecting each other. The angles across from each other will be both congruent and adjacent
What TYPE are angles of pairs of opposite and congruent angles formed by intersecting lines?
Adjacent angles
What is a pair of congruent angles that are formed when two lines intersect?
Vertical angel
If two intersecting lines form congruent adjacent angles then the lines are perpendicular?
Yes.
When 2 straight lines intersect the sum of the adjacent angles equals?
180 degrees
When two perpendicular lines intersect four congruent angles are formed?
yes, it makes four right angles.
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
