If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
midpoints |
|
intersects |
|
bisects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
Which of the following statements about a parallelogram is not true?
opposite sides and adjacent angles are equal |
|
the area of a parallelogram is base x height |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
|
a parallelogram is a quadrilateral |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
If a = 5, b = 2, c = 6, and d = 8, what is the perimeter of this quadrilateral?
| 16 | |
| 30 | |
| 21 | |
| 31 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 5 + 2 + 6 + 8
p = 21
What is 7a - 7a?
| 14 | |
| a2 | |
| 14a2 | |
| 0a |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
7a - 7a = 0a
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
pairs |
|
addition |
|
division |
|
exponents |
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.)
