Terms in this set (16)
Trigonometry
a branch of mathematics studying the relationships between angles and sides of triangles and other figures
Pythagorean Theorem
states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs.
45-45 Special Right Triangle
the legs are congruent and the hypotenuse is the product of the leg and the square root of 2
30-60 Special Right Triangle
the long leg is the product of the short leg and the square root of 3 and the hypotenuse is the product of the short leg and 2
Obtuse Triangle
c is the longest side, a and b are other lengths of the sides, and c squared is greater than the sum of a squared and b squared
Acute Triangle
c is the longest side, a and b are other lengths of the sides, and c squared is less than the sum of a squared and b squared
Sine Ratio
the ratio of the length of the leg opposite to an angle to the length of the hypotenuse of a right triangle
Cosine Ratio
the ratio of the length of the leg adjacent to an angle to the length of the hypotenuse of a right triangle
Tangent Ratio
the ratio of the length of the leg opposite to an angle to the length of the leg adjacent to an angle
hypotenuse
the side of a right triangle opposite the right angle and the longest side of a right triangle
adjacent leg
the side of the angle that is not the hypotenuse.
opposite leg
the side of a triangle that is not a side of a given angle
Pythagorean triples
a set of nonzero whole numbers a, b, and c that satisfy the Pythagorean Equation
Trigonometric ratio
a ratio of the lengths of two sides of a right triangle
angle of elevation
the angle formed by a horizontal line and the line of sight to an object above the horizontal line
angle of depression
the angle formed by a horizontal line and the line of sight to an object below the horizontal line
