Algebra: Chapter 10

Leg (10.1)

Each of the sides forming the right angle.

Converse (10.1)

Of a conditional switches the hypothesis and the conclusion.

Hypothesis (10.1)

The part following "if"

Conclusion (10.1)

The part following "then"

Hypotenuse (10.1)

The side opposite the right angle.

Angle of Elevation (10.6)

Is an angle from the horizontal up to a line of sight.

Extraneou Solution (10.4)

Is an apparent solution that does not satisfy the original equation.

Radical Equation (10.4)

Is an equation that has a variable in a radicand.

Pythagorean Theorem (10.1)

Named after the Greek mathematician Pythagoras, relates the lengths of the legs and the length of the hypotenuse.

Radical Expression (10.2)

An equation that has a variable

Conditional (10.1)

An if-then statement such as "If an animal is a horse, then it has four legs"

Conjugates (10.3)
