Constructions

To get started with Desmos Geometry, you'll need to know the available construction tools, as well as how to use them. When you've learn these tools, you can move on to learn about transformations.

Notes:

All constructions have these two settings: Color and Visibility, so they will not be mentioned in constructions' settings.

Labels can have parameters, found in the 'Measurement' tab for specialized objects, as well as text.

Primary Tools
Shown on the construction tab immediately, these are your core tools for creating awesome constructions.

Point
The point is used in all other constructions, in fact, all the other constructions have a minimum of two points. Points have two settings: Label and Lock Free Point. Lock free point makes the point immovable. Both settings are found in all points, even those constructed in other constructions.

Circle
Requires two points: the center and the radius.

Polygon
Made of potentially infinite points, to create one just keep creating points until which point you are satisfied with the shape, then finish the construction by closing the shape by joining the first and last points.

Angle
Requiring three points, the angle displays the angle made by these points and displays them, although you can remove the angle parameter from the angle label. To put it back navigate to the 'Measurements' tab available when clicking on the angle.

Segment
Requires two points, and forms a line between them. You can add the 'Length' parameter to your segment's label from the 'Measurements' tab.

Line
Requires two points. Similar to segments, however forms an infinite line in both directions.

Ray
Requires two points. Similar to lines, however forms an infinite line in one direction.

Vector
Requires two points. Similar to segment, however has the appearance of an arrow.

Arc
Requires three points. Create an arc between those three points.

Compass
Requires one pre-existing segment and a point. Creates a circle.

Midpoint
Requires one pre-existing segment. Creates a point at the middle of the segment. Works on rays as well.

Parallel Line
Requires a pre-existing line, segment, ray or vector and a point. Creates a line parallel to the original.

Perpendicular Line
Requires a pre-existing line, segment, ray or vector and a point. Creates a line perpendicular to the original.
