In the "old days" before computers had vdu's, it was amusing to generate shapes on the printer. One option for a right angle might be, in pseudo code,
For n= 1 to 15 step 1
Print "*"; carriage return

Print "";"";"******"
a 3 sided shape is a right angle triangle
A right angle triangle

an obtuse angle
a cube
