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

• All sides are of equal length

How do you calculate the area of a trapezoid?

• Multiply the height by the sum of the bases

• Divide the height by the sum of the bases

• Multiply the height by the difference of the bases

• Height times the sum of the bases divided by two

What is the area of a trapezoid with a height of 6 feet, base1 of 5 feet, and base2 of 9 feet?

• 42 feet squared

• 30 feet squared

• 45 feet squared

• 60 feet squared

How do you find the height of a trapezoid if the area and bases are known?

• Divide the area by the product of the bases

• Multiply the area by the sum of the bases and divide by two

• Use the area formula in reverse to solve for height

• Divide the area by the sum of the bases

What is the definition of a kite in geometry?
