A trapezoid is a quadrilateral with one set of __________ sides.
right angle |
|
equal angle |
|
equal length |
|
parallel |
A trapezoid is a quadrilateral with one set of parallel sides.
If side a = 9, side b = 2, what is the length of the hypotenuse of this right triangle?
| \( \sqrt{85} \) | |
| \( \sqrt{65} \) | |
| \( \sqrt{80} \) | |
| \( \sqrt{61} \) |
According to the Pythagorean theorem, the hypotenuse squared is equal to the sum of the two perpendicular sides squared:
c2 = a2 + b2
c2 = 92 + 22
c2 = 81 + 4
c2 = 85
c = \( \sqrt{85} \)
A coordinate grid is composed of which of the following?
origin |
|
all of these |
|
y-axis |
|
x-axis |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
If a = c = 9, b = d = 1, and the blue angle = 61°, what is the area of this parallelogram?
| 10 | |
| 16 | |
| 9 | |
| 24 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 9 x 1
a = 9
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°.
