Transformations and Trigonometry
What is rotational symmetry?
How many rotations it takes for a figure to return to its original position.
What is "c" in standard form?
c = the y-intercept
What does "k" stand for in inverse/direct variation?
The constant.
What is unique about equilateral triangles?
Congruent angles and sides. 60-60-60
What are some common probability models?
Cards, dice, and spinners.
What is the difference between an image and a pre-image?
Pre-images are the image before it is transformed.
What is the value of "i"?
Square root of -1.
What is the radical function parent function?
y = square root of x
What does CPCTC stand for?
Corresponding parts of congruent triangles are congruent.
What does union mean?
A OR B; combines the two sets
What can inverse trig. ratios find?
Missing angle measure.
Is 289 a perfect square?
Yes, 17 * 17.
What is the equation for direct variation?
k=y/x
Is AAS a congruence theorem?
Yes, two angles and a side opposite.
What does intersection mean?
A AND B; overlap of the two sets
Is a dilation a rigid tranformation?
No, it is non-rigid since the figures are no longer congruent.
What do "p" and "q" stand form in factored form?
The solutions, or zeros.
What is the equation for inverse variation?
y=k/x or k=y*x
What does similar mean?
The corresponding sides are proportional to each other, not congruent.
What does set notation look like?
What are the two types of special right triangles?
45-45-90 and 30-60-90
What does the formula b^2-4ac find?
The discriminant.
What does "h" stand for in a radical function/during transformations.
Horizontal shifts.
What are the three triangle SIMILARITY theorems?
AA, SSS, SAS
What does independent mean?
One event occurs and doesn't affect the second event.
