Draw-Geometry (v1.8.2)

This is drawing-app with simple UI and lot of useful built-in for Euclidean geometry without calculation. Moreover, you can find similar with GSP and Geogebra which I love to use during highschool.

This is Feuerbach theorem (Nine point circle tanglent incircle)

HOW TO

Just press this link and enjoy.

CUSTOMIZE

We have 6 main kind of object: Mouse, Point, Line, Circle, Conic and Transform that can find in the top of web app.

Mouse

In top-right we have 4 option:

• Normal: Only choose, draw point, line and circle.
• Eraser: This can hide only a single object.
• Show: This can show all objct which was eraser or hide.
• Hide: This is opposite of show.

Point

In top-right we have 4 option:

• Normal: Only draw a point.
• Midpoint: Draw midpoint between two points.

  Choose two point or choose one segment

• Intersect: Intersection of two lines.

  Choose two lines, two circle or one circle and one line (one line and one circle is similar)

Line

In top-right we have 4 option:

• Normal: Only draw a line.

  Choose two points

• Perpen: This is perpendicular line from one point to one line.

  Choose one point and one line (one line and one circle is similar)

• Parallel: This is parallel line of one point and one line.
• Segment: This is segment between two points.
• Angle: This is angle bisector.

Circle

In top-right we have 4 option:

• Normal: Only draw a circle.
• Circum: This is circumcircle go throught three points.
• Incircle: This is circle of triangle.

Conic

In top-right we have 5 option

• Normal: Only draw a conic
• Ellipse: Draw ellipse with two foci and one point
• Parabola: Draw parabola with one point and one line
• Hyper: Draw hyperbola with two foci and one point

COMMIT

I hope you follow this rule when commit anything new.
