|
Inside |
|

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.
When two lines intersect, adjacent angles are __________ (they add up to 180°) and angles across from either other are __________ (they're equal).
acute, obtuse |
|
obtuse, acute |
|
supplementary, vertical |
|
vertical, supplementary |
Angles around a line add up to 180°. Angles around a point add up to 360°. When two lines intersect, adjacent angles are supplementary (they add up to 180°) and angles across from either other are vertical (they're equal).
If the base of this triangle is 7 and the height is 9, what is the area?
| 31\(\frac{1}{2}\) | |
| 90 | |
| 32 | |
| 30 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 7 x 9 = \( \frac{63}{2} \) = 31\(\frac{1}{2}\)
Order the following types of angle from least number of degrees to most number of degrees.
acute, right, obtuse |
|
acute, obtuse, right |
|
right, acute, obtuse |
|
right, obtuse, acute |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
If a = 8, b = 8, c = 9, and d = 1, what is the perimeter of this quadrilateral?
| 19 | |
| 23 | |
| 21 | |
| 26 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 8 + 8 + 9 + 1
p = 26
