With Geometry: Constructions Tutor learn to make constructions with compass, pencil and straightedge. Learn constructions by watching animated demonstrations. Switch to the practice mode and make a construction yourself to test your knowledge and understanding. The application will check the construction when you’re done and tell you if you’re correct. Let the program confirm your constructions and build your confidence!

Smart objects snapping, automatic detection of objects intersections, a unique single touch compass, pinch-to-zoom, and an above-the-finger magnifying glass will make even a complex construction feel easy. There’s no need to use clumsy real world geometric tools and waste one sheet of paper after another to get a perfect result. Make all constructions with just one finger. Every action can be undone and you can restart at any moment. There is no need to aim. Smart snapping will do the job for you. Focus on learning and test your real knowledge, not your motor skills!

- Lines: copy of a segment, perpendicular bisector, division of a segment into equal parts, perpendicular line through a point on a line, perpendicular line through an external point, parallel line through a point.

Constructions tutor

I can't get the mail image or share image to work. Wonder what I am doing wrong!


Mechanical Drafter

This is just the thing for students of Art, Technical Drawling, Design, and other like professional trades. Even if you are just a hobbyist looking to up your game. I honestly have used and benefited from this app. I will be getting the full version next pay day! I hope this review helps anyone trying to decide on getting this app.

Constructions made simple

Great demos that are easy to follow. Nice having the ability to change speed & practice with a self check.
