More Triangle Appreciation
It’s been a great week for special triangles.
Six days ago was a rare Equilateral Triangle day, four days ago we appreciated the 10-12-10 triangle, and today, 10/16/10, gives us another triangle to admire.
It’s actually very closely related to the 10-12-10 triangle, which we saw is just two right triangles pasted together.
Just cut along the dotted altitude:
Now rotate the two pieces:
Stick them back together along their common side of length 6:
Now flip, and voila! Another triangle made by gluing two congruent right triangles together!
I’m running out of good triangles, so we may not appreciate another until December 10th.
