What is the Proof for Thale's Theorem? | Minute Math

What is the Proof for Thale's Theorem? In this online math video, we prove Thales Theorem. We use our knowledge of iscoceles triangles and circles to prove that a triangle inside of a circle will always have a 90 degree angle. This is the proof for Thales Theorem. #proofs #thalesthorem #minutemath #geometry #geometryproof #mathproof #proof #mathhelp #thales #lightboard #math #mathvideos

First time on your channel, the luminance of the text is great! Great explanation, thank you!

I think I am more impressed by his ability to left-hand write in reverse

Awesome proof, cleanly excecuted! Also throughout the whole video i was wondering how you got your written text to show up the correct way round.. is it flipped? No.. because your shirt is the right way round... im confused! 🤣

I draw 2 right angles inside the circle with the sides bisecting at the diameter and use the intersecting lines to find the center. Helps with drilling my wooden dowels and plaques in the center for mounting things!

is the video mirrored or is he writing in reverse?

Use of semicolon insinuates Computer Science knowledge
