The dimensions of this trapezoid are a = 4, b = 5, c = 6, d = 6, and h = 2. What is the area?
| 10 | |
| 11 | |
| 30 | |
| 18 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(5 + 6)(2)
a = ½(11)(2)
a = ½(22) = \( \frac{22}{2} \)
a = 11
If angle a = 63° and angle b = 23° what is the length of angle c?
| 78° | |
| 94° | |
| 103° | |
| 69° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 63° - 23° = 94°
A trapezoid is a quadrilateral with one set of __________ sides.
right angle |
|
equal angle |
|
parallel |
|

A trapezoid is a quadrilateral with one set of parallel sides.
A coordinate grid is composed of which of the following?
all of these |
|
y-axis |
|
x-axis |
|
origin |
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.
On this circle, a line segment connecting point A to point D is called:
radius |
|
chord |
|
circumference |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
