GeoGebra is a free math software that supports the learning and teaching of algebra, geometry and calculus. With GeoGebra you can draw function graphs, spatial geometry, and more.
GeoGebra has an intuitive interface but new users may feel confused with the math, drawing a bit complicated. So why don't we learn from the simplest things? The following article will guide you to get started with creating a basic parallelogram using GeoGebra.
Create a basic parallelogram in GeoGebra
To draw a basic geometric shape in GeoGebra, follow these steps:
Step 1 : Select the Line tool and create an arbitrary AB line by double clicking in Graphics View .
Step 2: Create a line BC with C as a new point.
Step 3 : Activate Parallel Line tool and create a line parallel to AB passing through point C.
- Hint : Select the tool, then click on point C and the line AB.
Step 4 : Create a line parallel to BC going through point A.
- Hint : Similarly, select the Parallel Line tool , click on point A and the line BC.
Step 5 : Select the Intersect tool and create the intersection D of the two lines you just created above.
Step 6 : Draw the parallelogram ABCD with the Polygon tool .
Step 7: Use the Move tool and drag the vertices of the parallelogram to change the size and position as you like.
Thus, with only 7 simple steps you have created a desired parallelogram. With GeoGebra, you can also manipulate even more complex drawings and calculations. Try exploring and experience!
