Geometry 3-2 Complete Lesson: Properties of Parallel Lines

Take Note: Summarize Postulate 3-1: The Same-Side Interior Angles Postulate. You may use the canvas to help illustrate your description.

Problem 1 Got It? If you know the measure of one of the angles, can you always find the measures of all 8 angles when two parallel lines are cut by a transversal? Explain.You may use the canvas to help illustrate your explanation.

Take Note: Summarize Theorem 3-1: The Alternate Interior Angles Theorem. You may use the canvas to help illustrate your description.

Take Note: Summarize Theorem 3-2: The Corresponding Angles Theorem. You may use the canvas to help illustrate your description.

Problem 2 Got It? Complete the proof on the canvas. Use a color other than black for your work.

Compare and Contrast: How are the Alternate Interior Angles Theorem and the Alternate Exterior Angles Theorem Alike? How are they different?

In Problem 2, you proved that angles 1 and 8, in the diagram below, are supplementary. What is a good name for this pair of angles? Explain.

Review Lesson 3-1: Drag each of the statements on the left into the appropriate category.

Review Lesson 2-2: Write the converse of the conditional statement and determine its truth value.If two angles are vertical angles, then they are congruent.

Vocabulary Review: Match each symbol with its meaning.

Vocabulary Review: Classify each angle as acute, obtuse, or right. You may need to zoom out to see all of the items. You can also place each item from the left column by selecting it (click it) then selecting (clicking on) the category for it.

Use Your Vocabulary: Use the diagram to complete each sentence on the right using the correct point from the left.

Use Your Vocabulary: Use the diagram to complete each sentence on the right using the correct item(s) from the left.

Reflection: Math Success
