### Transcript

• 1. Today’s Objectives • You will learn to use geometry tools. • You will learn to use a four step plan to solve problems that involve the perimeter and area of rectangles and parallelogramsKey Vocabularystraightedge perimetercompass formulaconstruction areamidpoint Four-step plan
• 2. straightedgeAn object used to draw astraight line, or to check if a lineis straight. It does NOT have tobe a ruler, just an edge that isperfectly straight.
• 3. Determine if the sides of the triangle are straight.Use a straightedge to determinewhich of the three segments atthe upper left forms a straightline with the segment at thelower right.
• 4. CompassA geometry tool used to draw arcs and circles.
• 5. You can use a compass to determine whichsegment is longer, AB or CD.
• 6. In Geometry, you will draw figures using only a compass and astraightedge. These drawings are called CONSTRUCTIONS. Youdo not use any standard measurements when doing aconstruction.This is a construction of a six-sided figure.
• 7. The center of a line segment is called its MIDPOINT. You can use thin paper (patty paper) to find the midpoint of a line segment.
• 8. FORMULAAn equation that shows how certain quantitiesare related.
• 9. ParallelogramA quadrilateral with opposite sides parallel.
