Section 5.5 Parallel Lines and Transversals 215 EXAMPLE 2 Using Corresponding Angles Use the fi gure to fi nd the measures of the numbered angles. PROPERTY 1: When two parallel lines are cut by a transversal, then corresponding angles are congruent. When two Angles in Parallel Lines happen, there are four types of congruent angles that are formed and can be used to solve for missing angles. What are Acute, Obtuse, Right, and Straight Angles? If two angles are complementary, that means that they add up to 90 degrees. Just remember: Always the same distance apart and never touching.. When two parallel lines are intersected by a third line — a transversal — corresponding pairs of angles are formed. Well, the first thing that we might realize is that, look, corresponding angles are equivalent. Introducing Transversals & Parallel Lines First, students will need to be able to identify angle pairs, then know the properties and relationships that exist when the lines that the tranversal intersects happen to be parallel. Take a look! 0 Downloads. Practice questions Use the figures and the given information to solve for the missing angles in the following questions. If we draw to parallel lines and then draw a line transversal through them we will get eight different angles. interior angles. Two angles are highlighted in each figure of this printable worksheet. 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. Alternate Interior Angles. If you can just give me an example that would be great or a link to a site that might help, I'd greatly appreciate it. interior angles.
