Angle bisector
Tap the point that is the vertex of the angle to be bisected (A) and press . Tap another point (B)
and press .
Polygon
The Polygon menu provides tools for drawing various polygons.
Triangle
Tap at each vertex, pressing after each tap.
Keyboard shortcut:
Isosceles Triangle
Draws an isosceles triangle dened by two of its vertices and an angle. The vertices dene one of the two
sides equal in length and the angle denes the angle between the two sides of equal length. Like
equilateral_triangle, you have the option of storing the coordinates of the third point into a CAS
variable.
isosceles_triangle(point1, point2, angle)
Example:
isosceles_triangle(GA, GB, angle(GC, GA, GB) denes an isosceles triangle such that one
of the two sides of equal length is AB, and the angle between the two sides of equal length has a measure
equal to that of ∡ACB.
