On this circle, a line segment connecting point A to point D is called:
circumference |
|
diameter |
|
chord |
|
radius |
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).
If angle a = 40° and angle b = 45° what is the length of angle c?
| 95° | |
| 82° | |
| 65° | |
| 81° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 40° - 45° = 95°
If a = 9, b = 2, c = 1, and d = 6, what is the perimeter of this quadrilateral?
| 20 | |
| 31 | |
| 26 | |
| 18 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 9 + 2 + 1 + 6
p = 18
If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
bisects |
|
intersects |
|
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 = 2, b = d = 5, what is the area of this rectangle?
| 10 | |
| 15 | |
| 3 | |
| 24 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 2 x 5
a = 10
