Geoboard

Hello guys! How are you?

I'm developing an app that simulates a geoboard. The description for a geoboard is "A geoboard is a mathematical manipulative used to explore basic concepts in plane geometry such as perimeter, area and the characteristics of triangles and other polygons. It consists of a physical board with a certain number of nails half driven in, around which are wrapped geo bands that are made of rubber. rubber bands can also be used. Wikipedia".

For this first release I worked on the layout and with the basic interactions that the player will have using the app, that are: Create a new polygon, add a new point to this polygon, remove a point from the polygon and delete the entire polygon.

How to play:

• The big button in the center creates a new polygon. Dang and drop the "elastic" to a pin on the board.
• When you add a new point it will be created above the last polygon point(I'm working on that).
• When removing a point the last point added will be deleted(I'm working on that).
• To select a polygon you must click on one of it's points
• When deleting the current polygon selected will be deleted

Version 0.3:

• Distance between "nails" increased from 50 to 100;
• Calculate the polygon perimeter;
• Calculate the polygon area.

Version 0.2:

• Point Identifier;
• Change polygon color;
• Now the new point is created between the last point and the first point.

Version 0.1:

• Basic interaction.

What do you think? Do you have any feedback?

Cheers!
