One arm is marked with a circular ruler showing degree measures from 0В° to 360В°. R An angle ruler is a tool with two transparent arms, linked by a rivet that allows them to swing apart to form angles of various sizes. The number of degrees that a figure rotates. The angle at point A on the triangle below is identified as angle BAC or в€ BAC. Each of the three angles below is formed by the joining of two rays. The sides of an angle are rays that have the vertex as a starting point.

The figure formed by two rays or line segments that have a common vertex. Sample: Analyze the following data to find the mean and the mode. Analyzing can involve providing a written summary supported by factual information, a diagram, chart, table, or a combination of these.Д®xamine, evaluate, determine, observe, investigate To think about and understand facts and details about a given set of information.

Then add the numerators and put the sum over the common denominator. Sample algorithm: To add two fractions, first change them to equivalent fractions with the same denominator. Some examples of algorithms are the rules for long division or the rules for adding two fractions. Mathematicians invent algorithms that are useful in many kinds of situations. AlgorithmДЄ set of rules for performing a procedure. In this rectangle, sides AB and AD are adjacent because they meet at vertex A. Other pairs of adjacent angles are a and c, b and d, and c and d. In the parallelogram below, a and b are adjacent angles. Two angles in a plane that share a common vertex and common side but do not overlap are adjacent angles. For example, 3 and -3 are additive inverses, and 1/ 2 and -1/ 2 are additive inverses. Two numbers, a and b, that satisfy the equation a + b = 0. Adding zero to any rational number results in a sum identical to the original rational number. Zero is the additive identity for rational numbers. Acute triangleДЄn acute triangle is a triangle with three acute angles.

For example, 24 is an abundant number because the sum of its proper factor is 36 1 + 2 + 3 + 4 + 6 + 8 + 12 = 36. Abundant numberДЄ nmber for which the sum of all its proper factors is greater than the number itself. Numbers that are the same distance from 0 have the same absolute value of 3. The absolute value of a number is its distance from 0 on the number line.
