Copy of Construct a Square
Constructing a Square in Geogebra
1. Click on the point icon on the toolbar and click to create two points named A and B. {Be careful to not place points too far apart.}
2. Join the two points by clicking on the line-segment icon in the line drop-down on the toolbar and clicking on A followed by B.
3. Choose the perpendicular line icon on the toolbar. Click on the line segment AB and then on point B to draw a line perpendicular to AB at B.
4. Create circle with a center at B and radius BA. Use the point tool to put a point at the intersection of the circle and the perpendicular line named C.
5. Choose the perpendicular line icon on the toolbar. Click on the line segment BC and then on point C to draw a line perpendicular to BC at C.
6. Create circle with a center at C and radius BC. Use the point tool to put a point at the intersection of the circle and the perpendicular line named D.
7. Use the line segment tool and join point B to point C, then point C to point D and point D to point A.
