Interior Angles Parallel Lines

As you can see the c shape may appear back to front but this doesn t affect the angle measurements.

Interior angles parallel lines. On parallel lines co interior or c angles add up to 180. In the above figure 3 4 5 6 are called interior angles since those angles lie in between two lines. An introduction to alternate corresponding and co interior angles in parallel lines parallel lines are lines which are always the same distance apart and never meet.

Notice that they are not adjacent angles next to one another sharing a vertex. Also same eight angles are formed by non parallel lines and transversal line. This exclusive worksheet presents nine questions wherein the measure of an exterior angle is depicted and another angle is indicated for practice.

The worksheet is specially designed for students of grade 8 and grade 9. Angles that are on the opposite sides of the transversal are called alternate angles e g. M 1 m 2 and m 3 m 4.

These lines are parallel because a pair of corresponding angles are equal. Alternate angles are inside the parallel lines but on different sides of the transversal. The interior angles that lie on the same side of the transversal are consecutive interior angles and those lying on either side of the transversal are alternate interior angles.

Co interior angles on parallel lines are supplementary add up to. Alternate interior angles are interior between the parallel lines and they alternate sides of the transversal. When the lines are parallel the alternate interior angles are equal in measure.

Arrowheads show lines are. Exterior angles in parallel lines worksheet two pairs of same side exterior angles and alternate exterior angles are formed when parallel lines are cut by a transversal. They make a u shape.
