- Card tricks with magic deck. Question: How does
and the Pythagorean Theorem (PT)
a2 + b2 = c2
triangles = 1/2 bh
Area of parallelogram= bh
Scaling: a linear scale change of r gives area
change of factor r2.
3 questions: running, moat, wind power...
Proof of the PT: Similar right triangles: c
= a2 /c
+ b2 /c
