the 3 exterior angles of any triangle add up to 360 degree.*
triangle inequality theorem
slope=change in y/change in x=rise/run
some quations will ask you to identify parts of the graph of a function. They may ask for the value of the function, or, as here, the maximum or minimum valuies of the function....q(x)is represented by the y- value.
distance between points
union & intersection of sets
is the set of elements that are in either or both.....set of elements common to both
is plug in the given values of
powers of negatives
a negative number raised to an even power yields a positive result.A negative number raised to an odd power yields a negative result.
powers of fractions
raising a fraction between 0 & 1 to a power yields a number smaller than the original.
exterior angles of triangles
An exterior angle of a triangle is equal to the sum of the remote interior angles.
a parallelogram has 2 pairs of parallel sides.opposite sides are equal. opposite angles are equal.consecutive angles add up to 180 degree.

parallel lines & transversals
A transversal across parallel lines forms 4 equal acute angles & 4 equal obtus angles.

one way is to re- express them with a common denominator.Another way is to convert them both to decimals.
