Force angle to be between 0 and 90 degress
I want to show an angle in my GeoGebra presentation, that lies between the two sides of two line, with the angle between them to have the size of any number from 0° to 90°.
Specifically, I want to visualize the angle between a curve and its perpendicular, and a line through the above intersection.
GeoGebra keeps displaying the obtuse angle.
Actually, if I define a new "point on object" on the two above mentioned lines. I can draw a different angle that span as I want it to. It just that this way I define too many objects on the algebra panel, and it makes the whole project cluttered and over-defined.
