|Acute triangle |Triangle with three acute angles; measures between | | |

| |0 and 90 degrees | | |

| | | | |

|Area of complex shapes |What is the area of this shape? | | |

| |[pic] | | |

| |The Answer | | |

| |Did you get 35cm2? Make sure you follow these | | |

| |steps: To find the area, you need to divide the | | |

| |shape into a rectangle and a triangle: | | |

| |[pic] | | |

| |The area of the rectangle is 5 × 4 = 20cm2. | | |

| |The area of the triangle is [pic] | | |

| |The base of the triangle is calculated by | | |

| |subtracting the base of the rectangle (4cm) from | | |

| |the total length of the shape (10cm). So 10cm - 4cm| | |

| |= 6cm. The total area is 20 + 15 = 35cm2. | | |

| | | | |

|Area of irregular shapes |There is not a general formula for finding the area| | |

| |of irregular shaped because all irregular shapes | | |

| |aren’t the same. The best method is to break down | | |

| |the shape into recognizable shapes and find the | | |

| |area of each shape and then the sum of all shapes. | | |

| | | | |

|Box and whisker plot |A diagram or graph using a number line to show the | | |

| |distribution of a set of data | | |

| |Displays the median, upper and lower quartiles, and| | |

| |the maximum and minimum values of the data | | |

| | | | |

|Equiangular triangle |having all sides congruent. EX. A triangle with | | |

| |three congruent sides is called an equilateral | | |

| |triangle. | | |

| | | | |

|Equilateral triangle |A triangle with 3 equal sides and e equal angles | | |

| | | | |

|Exponential notation |a superscript (something printed above the usual | | |

| |line of printing) used to indicate the number of | | |

| |times the base is used as a factor (if a positive | | |

| |exponent) or divisor (if a negative exponent) or | | |

| |which root is to be taken. EX. In fractional | | |

| |exponents the denominator indicates which root must| | |

| |be taken. | | |

| | | | |

|exponents |A small number placed to the upper-right of a | | |

| |number; shows the number of times the base number | | |

| |is multiplied by itself | | |

| | | | |

|Inequalities (number line) |Not equal in size, amount, or value | | |

| | | | |

|integer |A positive number, a negative number or zero but | | |

| |not a fraction or a decimal | | |

| | | | |

|Isosceles triangle |Triangle with two equal sides and two equal angles | | |

| | | | |

|Linear equation |A linear equation is an algebraic equation of the | | |

| |form | | |

| |[pic] | | |

| | | | |

| |involving only a constant and a first-order | | |

| |(linear) term. | | |

| | | | |

|Multi-step equations |Equation: a sentence of equality written in | | |

| |symbols. Each equation has 3 parts: 2 expressions | | |

| |separated by an equal sign. EX. A formula is an | | |

| |example of an equation. | | |

| |A multi-step equation has more than one step. | | |

| | | | |

|Obtuse triangle |Triangle with one obtuse angle; an obtuse angle | | |

| |measures between 90 and 180 degrees | | |

| | | | |

|opposite |Positive vs. negative; opposite numbers have the | | |

| |same numeral but have opposite signs | | |

| | | | |

|Percents (above 100, below 1) |a part of the whole expressed in hundredths, a rate| | |

| | | | |

|Pi (approximation i.e. 3.14, |Ratio of the circumference of a circle to its | | |

|22/7) |diameter | | |

| | | | |

|Rational numbers |A real number that can be written as: a ratio of | | |

| |two integers (fraction), excluding zero as a | | |

| |denominator, a repeating or terminating decimal, or| | |

| |an integer | | |

| | | | |

|Regular polygon |A polygon with all sides equal and all angles equal| | |

| |are regular | | |

| | | | |

|Right triangle |Triangle with one right angle; a right angle | | |

| |measures 90 degrees | | |

| | | | |

|Scale factor |A ratio between two sets of measurements | | |

| | | | |

|Scalene triangle |Triangle in which all three sides are a different | | |

| |length | | |

| | | | |

|Scatter plots |A graphical diagram with points plotted to show a | | |

| |relationship between two variables | | |

| | | | |

|similarity |Having the same shape but not necessarily the same | | |

| |size | | |

| | | | |

|Surface area |Total area of the surface of a three-dimensional | | |

| |object, measured in square units | | |
