Basics
100
the pairs of angles on opposite sides of the transversal but outside the two parallel lines.
What are alternate exterior angles?
100
when angle measures stay the same during a transformation.
What is angle preserving?
100
where the line crosses the y-axis.
What is y-intercept?
100
the action of moving around an axis or center.
What is rotation?
100
a real number that cannot be expressed as a ratio of integers. does not terminate, nor repeat.
What are irrational numbers?
200
two angles whose sum is 90°
What are complementary angles?
200
when the only difference is size (and possibly the need to move, turn or flip one around).
What is similar?
200
y = mx + b
What is slope intercept formula?
200
moving something from one place to another using a sliding motion.
What is translation?
200
a number that produces a specified quantity when multiplied by itself.
What is a square root?
300
angles that occupy the same relative position at each intersection where a straight line crosses two others.
What are corresponding angles?
300
translation, reflection, and rotation.
What is basic rigid motions?
300
where the line crosses the x-axis.
What is x-intercept?
300
A transformation in which a geometric figure creates a mirror image. A flip.
What is reflection?
300
the number that produces a given number when cubed.
What is cube root?
400
the pairs of angles on opposite sides of the transversal but inside the two parallel lines.
What are alternate interior angles?
400
exactly the same.
What is congruent?
400
m= y2 - y1/ x2 - x1
What is slope formula?
400
a change in size of a figure.
What is dilation?
400
A symbol for a number we don't know yet. It is usually a letter like x or y.
What is a variable?
500
two angles whose sum is 180°.
What are supplementary angles?
500
the opposite.
What is inverse?
500
an equation between two variables that gives a straight line when plotted on a graph. must be true and contain an equal sign.
What is a linear equation?
500
directional movement.
What is vector?
500
the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other sides. a2 + b2 = c2
What is the Pythagorean Theorem?
