Using the Geometry Window

When there is a Geometry window on the display, you can drag values and expressions to the Geometry
window to draw the graph or figure of the value or expression. You can also drag a figure from the Geometry
window to the work area, which displays the corresponding expression or value.
u To drag an expression from the work area to the Geometry window
0241 To input the expression
Tip:
The following table shows the types of expressions you can drop into the Geometry window. When the expression is
not recognized, Geometry displays it as text.
Dropping this into the Geometry window:
Linear equation in and
Equation of circle in and
Equation of ellipse in and
Equation of hyperbola in and
2-dimensional vector (2 rows × 1 column format)
Equation = ( )
