Drag F to create a family of parallelograms with the same base and the same height.​
Drag E along the line to create a family of parallelograms with the same height.
Measuring the Height of a Parallelogram.
Click on the point tool and create a point on the length of the parallelogram.​
Create another point directly opposite the point you created. ​
Create a third point at a vertex of the figure.​
Use the segment tool to connect the first 2 points you created.​
Use the angle tool to measure the insert the angle the segment makes with the base. Start from the last point and move clockwise.​
Adjust the vertical line to make 90 degrees with the base.​
Click on the distance tool and measure the height of the figure.
(A). Study the parallelograms below and answer the following question. You can click on the (+) to enlarge the figures if necessary.
(B). Study the examples and non-examples of bases and heights of parallelograms below.
Examples: The dashed segments in these drawings represent the corresponding height for the given base.
Non-examples: The dashed segments in these drawings do not represent the corresponding height for the given base.
Select all the statements that are true about bases and heights in a parallelogram.
(1). For each parallelogram here, use the SEGMENT tool to construct its base and height. Drag a label next to each segment to denote what it represents.
(2). For the parallelograms above, record these lengths in the table below. In the last row, write an expression (using b and h) for the area of any parallelogram.
