A(n) __________ is to a parallelogram as a square is to a rectangle.
quadrilateral |
|
trapezoid |
|
triangle |
|
rhombus |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
Solve 6a + 8a = 5a + 4z - 6 for a in terms of z.
| 1\(\frac{9}{10}\)z - \(\frac{3}{5}\) | |
| -4z - 6 | |
| \(\frac{9}{10}\)z - \(\frac{4}{5}\) | |
| -3\(\frac{1}{3}\)z - 2\(\frac{1}{3}\) |
To solve this equation, isolate the variable for which you are solving (a) on one side of the equation and put everything else on the other side.
6a + 8z = 5a + 4z - 6
6a = 5a + 4z - 6 - 8z
6a - 5a = 4z - 6 - 8z
a = -4z - 6
On this circle, line segment AB is the:
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 the length of AB equals the length of BD, point B __________ this line segment.
midpoints |
|
trisects |
|
intersects |
|
bisects |
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.
Order the following types of angle from least number of degrees to most number of degrees.
acute, right, obtuse |
|
right, obtuse, acute |
|
right, acute, obtuse |
|
acute, obtuse, right |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
