Sample Flashcard Questions & Answers

Showing 8 of 50 cards

Question #1 Active Recall

What is the sum of the interior angles of a polygon with n sides?

Answer & Explanation:

Sum = (n - 2) * 180 degrees

Question #2 Active Recall

What is the measure of each interior angle in a regular (equiangular) n-sided polygon?

Answer & Explanation:

Angle = ((n - 2) * 180) / n degrees

Question #3 Active Recall

What is the Pythagorean theorem, and when can it be applied?

Answer & Explanation:

a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse; it applies EXCLUSIVELY to right triangles.

Question #4 Active Recall

What are the side length ratios for a 45-45-90 special right triangle?

Answer & Explanation:

x : x : x*sqrt(2) (legs are equal, hypotenuse is leg * sqrt(2)).

Question #5 Active Recall

What are the side length ratios for a 30-60-90 special right triangle?

Answer & Explanation:

x : x*sqrt(3) : 2x (short leg opposite 30° is x, long leg opposite 60° is x*sqrt(3), hypotenuse is 2x).

Question #6 Active Recall

What are the basic trigonometric ratios for an acute angle theta in a right triangle (SOH CAH TOA)?

Answer & Explanation:

sin(theta) = Opposite / Hypotenuse; cos(theta) = Adjacent / Hypotenuse; tan(theta) = Opposite / Adjacent.

Question #7 Active Recall

What is the fundamental complementary angle trigonometric identity?

Answer & Explanation:

sin(x) = cos(90° - x) or in radians sin(x) = cos(pi/2 - x)

Question #8 Active Recall

What is the Pythagorean trigonometric identity?

Answer & Explanation:

sin^2(theta) + cos^2(theta) = 1
