If the length of AB equals the length of BD, point B __________ this line segment.
intersects |
|
trisects |
|
bisects |
|
midpoints |
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 a = c = 3, b = d = 9, and the blue angle = 61°, what is the area of this parallelogram?
| 27 | |
| 18 | |
| 20 | |
| 25 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 3 x 9
a = 27
If the base of this triangle is 6 and the height is 4, what is the area?
| 12 | |
| 32\(\frac{1}{2}\) | |
| 40 | |
| 36 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 6 x 4 = \( \frac{24}{2} \) = 12
A(n) __________ is two expressions separated by an equal sign.

expression |
An equation is two expressions separated by an equal sign. The key to solving equations is to 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.
A cylinder with a radius (r) and a height (h) has a surface area of:
4π r2 |
|
π r2h2 |
|
π r2h |
|
2(π r2) + 2π rh |
A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.
