In this mode you can measure areas of polygons and of conics. To measure the area of a polygon you simply click inside the polygon. To measure the area of a conic, you simply select it. In particular, you can use this mode to measure the area of a circle.

The Pythagorean theorem with area measurements

#### Synopsis

Select a polygon or a conic and obtain its area.

#### Caution

The area of a hyperbola is a complex number.

The contribution of a point to the area of a polygon is calculated with respect to its "winding" number. In particular, areas may become negative if the polygon is oriented clockwise. If the polygon is self-intersecting, areas may be zero.

You can measure the area of triangles in CindyScript using the area function.
