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 the base of this triangle is 9 and the height is 4, what is the area?
| 18 | |
| 37\(\frac{1}{2}\) | |
| 25 | |
| 38\(\frac{1}{2}\) |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 9 x 4 = \( \frac{36}{2} \) = 18
If a = 3, b = 3, c = 2, and d = 5, what is the perimeter of this quadrilateral?
| 18 | |
| 27 | |
| 13 | |
| 12 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 3 + 3 + 2 + 5
p = 13
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Odd |
|
Inside |
|
Last |
|
First |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
Which of the following statements about parallel lines with a transversal is not correct?
all acute angles equal each other |
|
angles in the same position on different parallel lines are called corresponding angles |
|
all of the angles formed by a transversal are called interior angles |
|
same-side interior angles are complementary and equal each other |
Parallel lines are lines that share the same slope (steepness) and therefore never intersect. A transversal occurs when a set of parallel lines are crossed by another line. All of the angles formed by a transversal are called interior angles and angles in the same position on different parallel lines equal each other (a° = w°, b° = x°, c° = z°, d° = y°) and are called corresponding angles. Alternate interior angles are equal (a° = z°, b° = y°, c° = w°, d° = x°) and all acute angles (a° = c° = w° = z°) and all obtuse angles (b° = d° = x° = y°) equal each other. Same-side interior angles are supplementary and add up to 180° (e.g. a° + d° = 180°, d° + c° = 180°).
