Algebra Readiness Builders Seventh Grade Vocabulary Absolute Value – is the distance from zero on the number line. Adjacent Angles – are a pair of angles immediately next to each other with one side in common. Base – is the number or expression in a power that is multiplied by itself. Circumference – is the distance around a circle. Congruent – means the same size and shape . Constant of Proportionality - is the constant value of the ratio of 2 proportional quantities (x & y). Conversion – is an exchange from one unit of measure to another. Complimentary Angles – are two angles whose sum is 90o. Diameter – is the distance across the circle passing through the center. Difference – is the answer when you subtract. Dilation – is a transformation that shrinks or stretches a figure. Distributive Property - a(b + c) = ab + ac. Algebra Readiness Builders Seventh Grade Vocabulary Experimental Probability - is the results when you actually toss a coin 100 times. Exponent - in the power 75 the 5 is the exponent.

Power - is an expression using a base and an exponent. Probability - is the number of favorable outcomes divided by the total of all possible outcomes. Algebra Readiness Builders Seventh Grade Vocabulary Product - is the answer when you multiply. Proportion - is an equation stating 2 ratios are equal. Quotient - is the answer when you divide. Radius - is the distance from the center of the circle to the edge. Rate - is a ratio of 2 measures that have different units. Ratio - is a comparison of numbers or variables that can be written in fraction form. Rational Number - is a ratio of 2 integers where the denominator ≠ “0”. Reciprocal – are two numbers whose product is 1. Reflection - is a mirror view. Similar Figures - is the ratio of corresponding side lengths are proportional. Straight Angle - is an angle that measures 180o. Sum - is the answer when you add. Algebra Readiness Builders Seventh Grade Vocabulary Supplementary Angles – are two angles whose sum is 180o. Term – is one part of an expression that includes a number, a variable, or product of both. Theoretical Probability - is the mathematically calculated chances of a specific event occurring. Total Surface Area - is the total area of the surface of a 3D object. Translation – is to move a figure in any direction without rotation. Transformation - is a change in position or size. Unit Rate - is a rate that has a denominator of 1 unit. Variable - is a letter used to represent a number in equations or expressions. Vertical Angles – are a pair of angles directly opposite of each other formed by the intersection of straight lines. Whole Numbers – are any natural number and “0”.
