Area of A Parallelogram

Use this worksheet to investigate how to find the area of a parallelogram.
Move point F describe what changes and what does not change about the parallelogram. [br]
What conjecture can you make about the formula for area for a parallelogram?[br](use the hint slider for help) [br]
Test the conjecture from question 2 with 5 different base and height combinations, record your results.

Area Of A Triangle

In this worksheet you will investigate how to find the area of a triangle.
Move point D so that the triangle is a right triangle, then move the Hint slider, describe the end result. [br]
Move point D to make an obtuse triangle and move the Hint slider, describe the end result. [br] (perform this task for an acute triangle as well)[br]
What conjecture can you make about the formula for area of a triangle? Test this conjecture with 5 different base and height combinations and record your results.
