    Complex Rational Expression
    A complex rational expression is a rational expression in which the numerator or denominator contains a rational expression.
    Extraneous Solution to a Rational Equation
    An extraneous solution to a rational equation is an algebraic solution that would cause any of the expressions in the original equation to be undefined.
    Proportion
    A proportion is an equation of the form \(ab=cd\), where \(b≠0,d≠0\). The proportion is read “\(a\) is to \(b\), as \(c\) is to \(d\).”
    Rational Equation
    A rational equation is two rational expressions connected by an equal sign.
    Rational Expression
    A rational expression is an expression of the form \(pq\), where \(p\) and \(q\) are polynomials and \(q≠0\).
    Similar Figures
    Two figures are similar if the measures of their corresponding angles are equal and their corresponding sides are in the same ratio.
