6.1.4 Classwork
Figures A, B, and C are [b]parallelograms[/b]. Figures D, E, and F are not parallelograms. Study the examples and non-examples.[br][br][img width=325,height=176]https://lh4.googleusercontent.com/joSD32orAKJU-4D8Pu6mAdrQHiobNZeqOAjd3K3j4KapyAyGLMr6beVUmKSw43cRhYGKFk4U8z-NjombeJd6-fXYCLuoUgYXxrETuyyhTPP_ROiHOOxRKR6dnrqMY_vKrlNkDJrI[/img][br][br] What do you notice about the number of sides that a parallelogram has?[br]
Pause for now!
Head back to Zoom & wait for directions.
Find the area of this parallelogram on the left. Explain your reasoning.
Change the parallelogram by dragging the green points at its vertices. Then find its area and explain your reasoning.
Find the area of each parallelogram. Show your reasoning.
