(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 tip--I agree.

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

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.
