Vertical Angles Corresponding Angles Alternate Interior Angles Or Alternate Exterior 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. How to find corresponding angles.
Exterior angles are also created by a transversal line crossing 2 straight 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. On parallel lines alternate or Z angles are equal.
1 and 5 are corresponding 1 and 8 are alternate exterior angles 2 and 6 are corresponding 2 and 3 are vertical equal.
In Fig a and b are a alternate exterior angles b corresponding angles c alternate interior angles d vertically opposite angles - Sarthaks. On parallel lines alternate or Z angles are equal. 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.
