The computer can be used for many things in mathematics these days. It has become very useful inconsturction of geometry. GSP is a computer program that is very useful in constructing images. I have made scripts in GSP that are short cuts to constructing certain things. The scripts I made are:
incircle and incenter
To use the scripts in GSP: click and hold the triangle and three dots button at the bottom of the tool bar. Go to the script you want to use and let go. Then draw what the script is for.
