If a = 4, b = 8, c = 6, and d = 1, what is the perimeter of this quadrilateral?
| 8 | |
| 17 | |
| 26 | |
| 19 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 4 + 8 + 6 + 1
p = 19
On this circle, a line segment connecting point A to point D is called:
diameter |
|
chord |
|
circumference |
|
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).

The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDOn this circle, line segment AB is the:
