If a = c = 7, b = d = 3, and the blue angle = 57°, what is the area of this parallelogram?
| 72 | |
| 21 | |
| 36 | |
| 63 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 7 x 3
a = 21
If angle a = 38° and angle b = 27° what is the length of angle c?
| 72° | |
| 115° | |
| 112° | |
| 91° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 38° - 27° = 115°
A coordinate grid is composed of which of the following?
origin |
|
y-axis |
|
x-axis |
|
all of these |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
pairs |
|
exponents |
|
addition |
|
division |
When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Which types of triangles will always have at least two sides of equal length?
equilateral and isosceles |
|
isosceles and right |
|
equilateral, isosceles and right |
|
equilateral and right |
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
