What are the angles in a parallel line?
All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs e.g. 3 + 7, 4 + 8 and 2 + 6. Angles that are in the area between the parallel lines like angle 2 and 8 above are called interior angles whereas the angles that are on the outside of the two parallel lines like 1 and 6 are called exterior angles .
What are the rules of parallel lines?
Parallel Lines. Lines are parallel if they are always the same distance apart (called “equidistant”), and will never meet. Just remember: Always the same distance apart and never touching. The red line is parallel to the blue line in each of these examples: Parallel lines also point in the same direction.
Do alternate interior angles equal 180?
Alternate angles are equal. d and f are interior angles. These add up to 180 degrees (e and c are also interior). Any two angles that add up to 180 degrees are known as supplementary angles.
What are the names of the angle pairs?
Angle Pair Names. Classify the angle pairs formed when lines are cut by a transversal as: AEA, AIA, CIA, CEA, CA, Vertical, or Linear Pair.
What are three examples of parallel lines?
Roadways and tracks: the opposite tracks and roads will share the same direction but they will never meet at one point.
What do angles with parallel lines add up to?
When a line crosses a pair of parallel lines, there are only two different angles, one acute and one obtuse. Recall these usual rules of angles (always true): Angles around a point add up to 360°. Angles on a straight line add up to 180°. Where straight lines cross, opposite angles are equal. With parallel lines there are 3 more rules:
What is the definition of parallel angles?
an angle formed between parallel lines by a third line that intersects them.
