How to find corresponding angles.

Vertical angles corresponding angles alternate interior angles or alternate exterior angles. Corresponding angles form are supplementary angles if the transversal perpendicularly intersects two parallel lines. Exterior angles on the same side of the transversal are supplementary if the lines are parallel. Parallel means that two lines are always the same distance away from each other and therefore will never meetParallel lines are marked with matching arrows as shown in the examples below.

1 and 5 are corresponding 1 and 8 are alternate exterior angles 2 and 6 are corresponding 2 and 3 are vertical equal. If two parallel lines are cut by a transversal corresponding angles must be congruent. You know that when two lines are parallel then a transversal gives rise to equal corresponding angles equal alternate interior angles and co-interior angles being supplementary.

One way to identify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles. Exterior angles are also created by a transversal line crossing 2 straight lines. Corresponding and alternate angles are formed when a straight line passes through two parallel lines.

Angles 2 and 7 are ALTERNATE and angles 1 and 8 are ALTERNATE. Similar to before angles 1 2 7 and 8 are EXTERIOR angles. On parallel lines alternate or Z angles are equal.

Learn how to identify corresponding angles alternate interior angles alternate exterior angles and consecutive interior angles in this free math video tut. As mentioned earlier a pair of vertical angles will always be congruent. Also like with interior angles the above exterior angles are equal when a transversal line crosses 2 parallel lines.

In review vertical angles are angles formed by the intersection of two lines while alternate interior angles alternate exterior angles corresponding angles and consecutive interior angles are formed by the intersection of two lines and a transversalDetermining if angles are vertical requires simple observation while determining other angle relationships can be done by asking yourself three questions. Conversely If any two lines are cut by a transversal such that Any pair of corresponding angles are equal or Any pair of alternate interior angles are equal or. Given the diagram identify the transversal and classify each pair of angles as corresponding alternate interior alternate exterior or consecutive interior angles vertical angles and linear pairs.

Similarly interior angles are supplementary if the two lines are parallel. Answers to question. In review vertical angles are angles formed by the intersection of two lines while alternate interior angles alternate exterior angles corresponding angles and consecutive interior angles are.

But the story is a little different when observing corresponding alternate interior alternate exterior or consecutive interior angles. No matter what the diagram looks like each pair of vertical angles will always have the same measurement. Solving problems involving parallel lines knowing the types of angles are either corresponding alternate interior same side interior alternate exterior or alternate exterior anglesalso review of postulate.

Corresponding and Alternate Angles. Look at the blue lines demonstrating the shape - the Z may be back to front as in the second example but the principle is the same. In Fig a and b are a alternate exterior angles b corresponding angles c alternate interior angles d vertically opposite angles - Sarthaks.
