Draw a right triangle

Syntaxe

triangle_right( cx=200, cy=200, a=100, b=100, angle=PI , from=true , stroke="#000000", fill="#FFA000", weight=4);

Arguments

Name	Required	Default	Description
`cx`	yes	-	x-coordinate of the reference point
`cy`	yes	-	y-coordinate of the reference point
`a`	yes	-	length of side A (Cathetus1, adjacent to right angle)
`b`	yes	-	length of side B (Cathetus2, adjacent to right angle)
`angle`	yes	-	rotation angle in radians
`from`	-	true	true: ref point is right angle (by default), false: ref point is hypotenuse center,
`draw`	-	true	If false, return a list of points, and don't draw (stroke, fill & weight are ignored)
`stroke`	-	#000000	Stroke color
`fill`	-	#FFFFFF	Fill color
`weight`	-	1.00	Stroke weight (thickness)
