Usage
spt(A,B)
Arguments
A,B

The degrees of two of the three angles of a triangle.

Details

When the original triangle is an acute triangle, the area of the smallest SPT/PT to be drawn is determined by (tol * S), where S is the total area for plotting. No restriction is applied to iter.

If the original triangle is an obtuse triangle, the largest value of iter is 12.

tol: A stopping creiteria to draw the sub-SPT. Default value 0.0001.

Value

The dimension of the SPT will be returned if the original triangle is an acute triangle.

The viewport of showing the SPT/ST "abc" can be changed by changing the value of abc$viewport.
