(A squared + B squared = c) (square root)
Two identical right triangles with sides of
6x8 hyp =10
Twenty miles apart.

Dear L. P. Skeen,
Twenty Miles.
Tip. When faced with a geometric or trigonometric problem, draw a =
picture to sort out the ideas. then do the math. If you make a scale =
diagram you can check your own answers.
Best regards,
Ivor Lewis.

Good tipI agree.

Uh, ohcareful now!! That's how people "square the circle," and probably
how the Indiana Legislature felt justified to decree Pi to be twentytwo
sevenths! This latter was done to make math easier for the school children!

that one :)

a right triangle with three sides in ratio of 3:4:5 or 5:12:13
is most often used in school math quiz as they are the two smallest
pythagorean triples (a trio of whole numbers that satisfies pythagorean
theorem). then 8:15:17, .....
triangles with sides in ratio of 1:1:sqrt(2) and 1:sqrt(3):2 are
next two most often used right triangles (with 45 degrees and
60/30 degrees angles) in school math, geometry and/or trigonometrics.
students don't have to spend their precious time in exam in
computing square roots of some ugly(?) numbers. answers are
simple and elegant, mostly. especially in math quiz.
(big smile :) and with good math teachers.
