Module 8 Flashcards
The side of a triangle that is opposite the right triangle
Hypotenuse
For any right triangle, the sum of the squares of the lengths a and b of thw legs equals the square of the length of c, the hypotenuse
Pythagorean theorem
A right triangle woth at least two congruent sides
Isosceles right triangle
A square root of a number n is a number m which, when multiplied by itself, equals n
Square root
The two sides of a right triangle that form the right angle
Legs
A triangle with one right angle
Right angle
The sides next to the right angle in a right triangle. The adjacent side cannot be the hypotenuse
Adjacent sides
This side will always be the longest side of the right triangle. It is also known as the hypotenuse
Opposite side
A number that can be written as a/b were a and b are integers and b =0 the decimal form either terminates or repeats
Rational numbers
A real number that cannot be written as a quotient of two integers. The decimal form neither terminates or repeats
Irrational number
