On this circle, line segment AB is the:
chord |
|
circumference |
|
diameter |
|
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 a = c = 9, b = d = 5, what is the area of this rectangle?
| 6 | |
| 45 | |
| 12 | |
| 7 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 9 x 5
a = 45
A(n) __________ is to a parallelogram as a square is to a rectangle.
rhombus |
|
trapezoid |
|
quadrilateral |
|
triangle |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
If angle a = 29° and angle b = 56° what is the length of angle c?
| 88° | |
| 66° | |
| 93° | |
| 95° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 29° - 56° = 95°
If side x = 13cm, side y = 15cm, and side z = 14cm what is the perimeter of this triangle?
| 30cm | |
| 23cm | |
| 42cm | |
| 29cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 13cm + 15cm + 14cm = 42cm
