When are alternate interior angles congruent?
When two parallel lines are both intersected by a tranversal which is a nonvertical line, otherwise all angles formed by that intersection are right angles.
If two parallel line are intersected by a transversal line what patters can you expect to find in the measures of angles formed?
If the transversal is at right angles, then all the angles will be right angles. If not, there will be only two different measures between the eight angles formed. These will alternate.
Can all alternate interior and corresponding angles formed by two parallel lines and a transversal be congruent?
Sure. Just as long as the transversal is perpendicular to the parallel lines.
How many pairs of alternate interior angles are formed by two lines that are intersected by a transversal?
Providing that the lines are parallel that the transversal passes through then it will have two equal alternate angles that are on opposite sides of the transversal.
Which types of angles are always congruent?
vertical angles are always congruent...they are two nonadjacent angles formed by intersecting lines. Vertical angles are congruent..or equal in measure
Corresponding angles formed when parallel lines are intersected by a transversal are congruent?
true

A pair of angles formed by two lines intersected by a third?
There are at least 28 different pairs of angles: 66 if the first two lines are not parallel. Your question needs to be more specific as to which angles you mean.

Sure. Just as long as the transversal is perpendicular to the parallel lines.

A pair of angles formed by two lines intersected by a third line?
these angles are called intersecting lines
What kind of angles are pairs of opposite and congruent angles formed by intersecting lines?
Angles that are pairs of opposite and congruent lines formed by intersecting lines are intersections
Which types of angles are always congruent?
vertical angles are always congruent...they are two nonadjacent angles formed by intersecting lines. Vertical angles are congruent..or equal in measure
What angles are formed on the inside of parallel lines?
No angles are formed on the inside of parallel lines because they do not intersect. That is the definition of parallel.
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 TYPE are angles of pairs of opposite and congruent angles formed by intersecting lines?
Adjacent angles
