In this section, we observe the PEDAL triangle and the SIMSON line. Click here for a GSP version of how to create a PEDAL triangle. You can also click here if you want to see a non-GSP write up on the same.
The PEDAL triangle assumes different shapes and even collapses into a line (the SIMSONS line) depending on its location with reference to the parent triangle. Click here to see some such positions.
