Which of the following statements about a parallelogram is not true?
opposite sides and adjacent angles are equal |
|
a parallelogram is a quadrilateral |
|
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 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 = -7 and z = -9, what is the value of -8a(a - z)?
| 112 | |
| 224 | |
| 210 | |
| -18 |
To solve this equation, 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.)
-8a(a - z)
-8(-7)(-7 + 9)
-8(-7)(2)
(56)(2)
112
If the base of this triangle is 5 and the height is 6, what is the area?
| 66 | |
| 15 | |
| 60 | |
| 82\(\frac{1}{2}\) |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 5 x 6 = \( \frac{30}{2} \) = 15
If the length of AB equals the length of BD, point B __________ this line segment.
midpoints |
|
intersects |
|
bisects |
|
trisects |
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.
The dimensions of this cube are height (h) = 4, length (l) = 7, and width (w) = 7. What is the volume?
| 72 | |
| 90 | |
| 196 | |
| 32 |
The volume of a cube is height x length x width:
v = h x l x w
v = 4 x 7 x 7
v = 196
