GeoGebra
📝Designing Quadrilateral Polygon using GeoGebra 1. Concept skills It is a polygon with four sides. It has four vertex and four angles 2. Process skills 1. Create the point A using the new point tool 2. Draw line segment AB using segment between two points 3. Click a perpendicular line tool to draw a perpendicular line 4. Click on the line drawn in step 6 to draw a perpendicular line. (After clicking drag a line to point 5. From point B draw a circle through point A using the Circle with Centre through a Point tool 6. Now add a new point C on the intersection point. 7. Repeat step 8 to draw a perpendicular line. (This time drag a line to point A) 12. From A draw a circle through B using the Circle with Centre through a Point tool 8. Now add a new point D on the intersection point 9. Now click the polygon tool and click on point A and drag the line to point B then to point C and finally to point D to make a square. 10. Hide unnecessary objects by right-clicking th
