Presentation transcript:

10.2: Area of Trapezoids, Rhombuses, and Kites

What is the approximate area of Nevada?

Where the height is the perpendicular distance between the bases

What is the area of this trapezoid?

What is the area of this trapezoid?

What is the area of this kite?

What is the area of this rhombus?

10.3: Area of Regular Polygons

If you circumscribe a circle around a polygon, the radius of the polygon is the distance from the center to a vertex, and the apothem is the perpendicular distance from the center to a side

The red line is an apothem…what are the angle measures shown?

What does it mean for two shapes to be congruent? What are the areas of these trapezoids?

What is the area of this decagon?

What is the area of this octagon?

What is the area of this hexagon?
