-
Bisector
-
Median
-
Perpendicular
-
Tangent
A
Correct answer
Explanation
A bisector is a mathematical concept that refers to a line, ray, or plane that divides a line segment, angle, or geometric figure into two equal parts.
What is the Pythagorean theorem?
-
a^2 + b^2 = c^2
-
a^2 - b^2 = c^2
-
a^2 + b^2 = c
-
a^2 - b^2 = c
A
Correct answer
Explanation
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

What is the reciprocal identity for sine?
-
sin(x) = 1/csc(x)
-
sin(x) = 1/sec(x)
-
sin(x) = 1/tan(x)
-
sin(x) = 1/cot(x)
A
Correct answer
Explanation
The reciprocal identity for sine is sin(x) = 1/csc(x).
What is the product-to-sum identity for sine and cosine?
-
sin(x)cos(y) = (sin(x+y) + sin(x-y))/2
-
sin(x)cos(y) = (sin(x+y) - sin(x-y))/2
-
sin(x)cos(y) = (cos(x+y) + cos(x-y))/2
-
sin(x)cos(y) = (cos(x+y) - cos(x-y))/2
A
Correct answer
Explanation
The product-to-sum identity for sine and cosine is sin(x)cos(y) = (sin(x+y) + sin(x-y))/2.
Which of the following is the product-to-sum identity for cosine and sine?
-
cos(x)sin(y) = (sin(x+y) - sin(x-y))/2
-
