Exploring Area Calculations for Trapezoids and Kites

Mrs. Zimmerman teaches 6th graders about calculating the area of trapezoids and kites. She explains the properties of trapezoids, including parallel and non-parallel lines, and provides a formula for finding their area. The lesson includes examples of calculating area and finding missing dimensions. The video also covers kites, explaining their properties and two methods for calculating area, focusing on using diagonals. Finally, the lesson discusses composite figures, combining trapezoids and kites, and emphasizes the importance of memorizing formulas for future use.

What defines a trapezoid?

• A shape with all sides parallel

• A shape with all sides of equal length

• A shape with one set of parallel lines

• A shape with no parallel lines

Which statement is true about the properties of a trapezoid?

• Both pairs of opposite sides are parallel

• Only one pair of opposite sides is parallel

• No sides are parallel
