unit 1.2 study guide
What do I need to know before I take the test? What should I have in my notes before I take the test? Here is your list of terms and tasks that you should know:
- What is a transversal?
- When there is a transversal, what types of angles are created?
- If two lines are parallel and they are cut by a transversal, what is true about corresponding angles, alternate interior angles, and same-side interior angles?
- What is a corresponding angle? What are two facts we know about corresponding angles involving parallel lines?
- What is an alternate interior angle? What are two facts we know about alternate interior angles involving parallel lines?
- What are same-side interior angles? What are two facts we know about same-side interior angles involving parallel lines?
- What are vertical angles? What is a fact we know about vertical angles?
- What are linear pairs? What is a fact we know about linear pairs?
- You should be able to identify the above angles. Have examples in your notes.
- What are supplementary angles?
- What is true about the interior angles of a triangle? Have this written as a a fact you can use in a proof.
- What is true about the exterior angle of a triangle? You should have this written as a fact you can use in a proof.
- What is true about angles about a point?
- What is true about adjacent angles on a line?
- What is an auxiliary line and how do we use it?
- How do you write a proof?
- Make sure you can use all the information here as a mathematical reason when finding unknown angles.
