3 4 parallel lines and transversals 131 same side interior angles theorem words if two parallel lines are cut by a transversal then same side interior angles are supplementary. If you think of it as one parallel line is the exact copy of the other it make since that the angles formed from the cut of the transversal will be an exact copy as well.

### Some of the worksheets for this concept are 3 parallel lines and transversals parallel lines transversals work work section 3 2 angles and parallel lines parallel lines transversals 8th grade geometry work parallel lines cut by a transversal parallel lines and transversals mathematics.

**Parallel lines and transversals worksheet if two parallel lines are cut by a transversal then**. Ma3 1 ma5 5 180 8 ma4 1 ma6 5 180 8 3 6 t k 4 j 5 theorem 3 7 use algebra with angle relationships. List each pair of vertical angles. This additional line is called a transversal.

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. If two parallel lines are cut by a transversal then each pair of sameside exterior angles are a. So when a transversal cuts through any set of parallel lines it forms sets of congruent angles and supplementary angles.

Symbols if j i k then the following are true. Parallel lines cut by a transversal lines displaying top 8 worksheets found for this concept. Students must have an understanding of alternate interior alternate exterior corresponding c.

Parallel lines cut by a transversal are formed when two parallel lines are intersected diagonally by an additional line. If two parallel lines are cut by a transversal then the pairs of same side interior angles are supplementary. If two lines are cut by a transversal so that same side interior angles are congruent supplementary complementary then the lines are parallel.

The map shows some paths through a corn maze. When two parallel lines are cut by a transversal what angle displaying top 8 worksheets found for this concept. Path b is parallel to path c.

Use the diagram to answer the following questions. Some of the worksheets for this concept are work section 3 2 angles and parallel lines sections proving lines then we can state mathlinks grade 8 student packet 12 lines angles and geometry notes parallel lines transversals angles mathematics capstone course parallel lines cut. List each pair of corresponding.

Follow the steps to illustrate the postulate and use it to find angle measures. If two lines are cut by a transversal so that alternate interior angles are congruent supplementary complementary then the lines are parallel. The first type of congruent angle formed by angles in parallel lines are vertical angles.

B identify the pairs of same side interior angles. A draw two parallel lines and a transversal and number the angles formed from 1 to 8. Parallel lines cut by a transversal coloring activity this is a fun way for students to practice solving problems related to parallel lines cut by a transversal all while coloring a vibrant beach scene.

Well when two parallel lines are cut by a transversal i e get crossed by a third line then not only do we notice the vertical angles and linear pairs that are subsequently formed but the following angle pair relationships are created as well.
