|
parallel
|
two lines going in the same direction that are equal distant apart and not touching
|
|
|
hypotenuse
|
the longest side of a right angle triangle, opposite the right angle
|
|
|
triangle - right angled
|
one angle is 90 degrees and the other two are complementary angles.
(for examples: Angles: 90, 70, 20) |
|
|
angles - supplementary
|
the sum of two angles add up to 180 degrees and together they make a straight angle (don't have to be adjacent)
|
|
|
angles - complementary
|
the sum of two angles add up to 90 degrees (don't have to be adjacent)
|
|
|
congruent
|
when one shape can become another using turns, flips and/or slides, then the two shapes are congruent
|
|
|
rotation
|
to turn around a center:
The distance from the center to any point on the shape stays the same. Every point makes a circle around the center. |
|
|
translation
|
move in the same direction and the same distance
|
|
|
reflection (x axis)
|
mirror line on the x-axis, change the (x,y) to (x,-y)
|
|
|
commutative property
|
you can swap numbers over and still get the same answer when you add, or when you multiply.
2 + 3 = 3 + 2 |
|
|
associative property
|
it doesn't matter how you group the numbers (i.e. which you calculate first) when you add, or when you multiply.
a + (b + c) = (a + b) + c |
|
|
distributive property
|
for all real numbers, a, b, and c
a(b + c) = ab + ac |
|
|
transversal
|
a line that cuts across parallel lines
|
|
|
GCF
greatest common factor |
the largest number that factors evenly into two or more larger numbers
|
|
|
polynomial
|
An expression that is a number, a variable, or the product of a number and one or more variables
|
|
|
pythagorean theorem
|
state formula
|
|
