BONUS Closure assignment:
All Chapter 2 Closure problems starting with 2-123 and ending with 2-130

Topics to Review for Chapter 2 Test:

• Angle Relationships and their Rules
• Straight Angle Pair (windshield wiper) - Supplementary
• Vertical Angles - Congruent
• Corresponding Angles - Congruent
• Alternate Interior Angles - Congruent
• Same-Side Interior Angles - Supplementary
• Are the lines parallel?
• Areas of:
• Triangles = (1/2)(b)(h)
• Drawing in the height - train method
• Height must be:
• 1. Coming down from the opposite vertex (the vertex across from the base)
• 2. Forming a right angle at the base.
• Parallelograms = (b*h)
• Same formula as a rectangle. But remember the HEIGHT in a PARALLELOGRAM is not a side length, it is an invisible line inside of the parallelogram that forms right angles. It is only an actual side length if you parallelogram is a RECTANGLE.
• Trapezoids = (1/2)(b1+b2)(h)
• Pythagorean Theorem (ONLY) works for right triangles.
• Triangle Inequality
