problem solving w/ Geometry
measuring angles
each min is subdivided into 60 sec of arc
full circle is 360 degrees
each degree subdivided 60 min of arc
longitude & latitude
line of latitude
equator
line of longitude
prime meridian
angular size & distance
angular size = physical size x 360 degrees/ 2(pi) x distance
similar triangles
a/a^1=b/b^1=c/c^1
angle a = angle A, angle b = angle B, angle c = angle C
pitch, grade & slope
grade is %
slope = rise/run
pitch = slope
pythagorean theorem
a^2+b^2 = c^2
optimization problems
seek best possible solution
