If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
intersects |
|
midpoints |
|
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.
The dimensions of this cube are height (h) = 2, length (l) = 6, and width (w) = 5. What is the surface area?
| 108 | |
| 88 | |
| 104 | |
| 38 |
The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):
sa = 2lw + 2wh + 2lh
sa = (2 x 6 x 5) + (2 x 5 x 2) + (2 x 6 x 2)
sa = (60) + (20) + (24)
sa = 104
If a = 6, b = 6, c = 1, and d = 4, what is the perimeter of this quadrilateral?
| 17 | |
| 20 | |
| 21 | |
| 24 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 6 + 6 + 1 + 4
p = 17
Which of the following statements about a triangle is not true?
perimeter = sum of side lengths |
|
area = ½bh |
|
sum of interior angles = 180° |
|
exterior angle = sum of two adjacent interior angles |
A triangle is a three-sided polygon. It has three interior angles that add up to 180° (a + b + c = 180°). An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite (d = b + c). The perimeter of a triangle is equal to the sum of the lengths of its three sides, the height of a triangle is equal to the length from the base to the opposite vertex (angle) and the area equals one-half triangle base x height: a = ½ base x height.
What is the area of a circle with a radius of 5?
| 25π | |
| 5π | |
| 9π | |
| 36π |
The formula for area is πr2:
a = πr2
a = π(52)
a = 25π
