Which of the following statements about a parallelogram is not true?
the area of a parallelogram is base x height |
|
a parallelogram is a quadrilateral |
|
opposite sides and adjacent angles are equal |
|
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 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.
If angle a = 38° and angle b = 65° what is the length of angle c?
| 77° | |
| 81° | |
| 84° | |
| 91° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 38° - 65° = 77°
The dimensions of this cube are height (h) = 6, length (l) = 9, and width (w) = 7. What is the volume?
| 378 | |
| 56 | |
| 108 | |
| 144 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 9 x 7
v = 378
Which of the following is not true about both rectangles and squares?
the area is length x width |
|
all interior angles are right angles |
|
the lengths of all sides are equal |
|
the perimeter is the sum of the lengths of all four sides |
A rectangle is a parallelogram containing four right angles. Opposite sides (a = c, b = d) are equal and the perimeter is the sum of the lengths of all sides (a + b + c + d) or, comonly, 2 x length x width. The area of a rectangle is length x width. A square is a rectangle with four equal length sides. The perimeter of a square is 4 x length of one side (4s) and the area is the length of one side squared (s2).
