pythagorean : a set of nonzero whole numbers (a,b,c) that satisfy the Pythagorean theorem; common triples are (3,4,5) (5,12,13) (8,15,17)
tangent : the ____of an acute angle of a right triangle is the ratio of the length of the opposite leg to the length of the adjacent leg
sine : the _______ of an acute angle of a right triangle is the ratio of the length of the opposite leg to the length of the hypotenuse
cosine : the _____ of an acute angle of a right triangle is the ratio of the length of the adjacent leg to the length of the hypotenuse
elevation : the angle of ______ is formed by a horizontal line and the line of sight to an object above the horizontal line
depression : the angle of _____ is formed by a horizontal line and the line of sight to an object below the horizontal line
Pythagorean : Theorem that states in a right triangle, the sum of the squares of the lengths of the legs equals the square of the length of the hypotenuse; The equation=a²+b²=c²
right : If c² = a² + b² then the triangle is a ________ triangle.
acute : If c² < a² + b² then the triangle is an _________ triangle.
obtuse : If c² > a² + b² then the triangle is an _________ triangle.
two : In a 30-60-90 triangle, the length of the hypotenuse is __ times the length of the shorter leg
three : In a 30-60-90 triangle, the length of the longer leg is the square root of ____ times the length of the shorter leg.
two : In a 45-45-90 triangle the length of the hypotenuse is is the square root of ____ times the length of the leg
astronomy : the two Greek mathematicians that created the discipline of trigonometry did so mainly to study
