Acute triangle
Triangle with three acute angles; measures between 0 and 90 degrees
Area of complex shapes
What is the area of this shape?
one side = 4cm
one side = 5 cm
one side = 10 cm

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:

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

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.
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
Isosceles triangle
Triangle with two equal sides and two equal angles
Linear equation
A linear equation is an algebraic equation of the form
y=ax+b


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, 22/7)
Ratio of the circumference of a circle to its diameter
Pi (approximation i.e. 3.14, 22/7)
Ratio of the circumference of a circle to its diameter
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
A graphical diagram with points plotted to show a relationship between two variables
Surface area
Total area of the surface of a three-dimensional object, measured in square units
