Geometry parallel lines proofs worksheet.

Angles, parallel lines, & transversals. Parallel lines are lines in the same plane that go in the same direction and never intersect. When a third line, called a transversal, crosses these parallel lines, it creates angles. Some angles are equal, like vertical angles (opposite angles) and corresponding angles (same position at each intersection).Proving Parallel Lines Worksheet MATH MONKS O Prove the lines c and d are parallel. 13 Given: Zl = Q Statements Reasons.

The Proof Process 1. Write the conjecture to be proven. 2. Draw a diagram if one is not provided. 3. State the given information and mark it on the diagram. 4. State the conclusion of the conjecture in terms of the diagram. 5. Plan your argument and prove your conjecture. Mark the diagram and answer the questions about the following proof.The first one focuses on angles, the second on lines and angles. The third one puts it all together. Homework 1 - We can see that ∠ABD and ∠CBD form a linear pair, so they are supplementary to each other. Homework 2 - Vertical angles are equal is the lead here. Homework 3 - Knowing that two lines are parallel, you can learn a lot.
