Point, segment, ray, line
Pick two points and the figure is created exactly between them. Intersections are marked automatically.
Dynamic geometry
Draw, drag, see the proof.
Geometry no longer sits still on paper: when one point moves, everything attached to it moves too.
01
Drawing tools
Start from the basics.
Polygon, regular polygon, circle, angle
Interior angles always add up correctly, and each interior angle gets its own colour and fill.
Draw with measures
Draw a segment by typing its length, an angle by its degrees, a triangle by its three sides.
Construction tools
Classic constructions, one tap away.
Midpoint
Perpendicular line
Parallel line
Perpendicular bisector
Angle bisector
Intersection
Diameter
Radius
Tangent
02
Construction and measurement
Classic constructions and live measurements.
Midpoint, perpendicular, parallel, bisectors
Clean figures with adjustable, limited-length lines.
Diameter, radius, tangent, central and inscribed angle
Every circle topic is draggable.
Angle, distance, area
Unit label is cm, mm, m or in; the measure on the page is kept.
03
Transformations
Reflect, translate or enlarge a figure.
Reflection
Move the mirror line and the image follows.
Translation
Choose the vector ends and the figure slides by that amount.
Scaling
Pick a centre point, type the ratio; a negative ratio enlarges to the opposite side.
Function graph
Type it, and the graph is drawn with a pen.
Type the function and the axes and curve appear on the page instantly. Change the equation and the curve is redrawn.
