If the length of AB equals the length of BD, point B __________ this line segment.
midpoints |
|
trisects |
|
bisects |
|
intersects |
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.
Solve for c:
8c - 8 = 6 - 5c
| \(\frac{5}{8}\) | |
| -1\(\frac{2}{7}\) | |
| 1\(\frac{1}{13}\) | |
| \(\frac{7}{8}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
8c - 8 = 6 - 5c
8c = 6 - 5c + 8
8c + 5c = 6 + 8
13c = 14
c = \( \frac{14}{13} \)
c = 1\(\frac{1}{13}\)
If a = 2, b = 6, c = 5, and d = 3, what is the perimeter of this quadrilateral?
| 13 | |
| 16 | |
| 31 | |
| 24 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 2 + 6 + 5 + 3
p = 16
If a = c = 8, b = d = 7, and the blue angle = 61°, what is the area of this parallelogram?
| 45 | |
| 27 | |
| 8 | |
| 56 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 8 x 7
a = 56
If angle a = 30° and angle b = 28° what is the length of angle c?
| 113° | |
| 96° | |
| 105° | |
| 122° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 30° - 28° = 122°
