A(n) __________ is to a parallelogram as a square is to a rectangle.
quadrilateral |
|
triangle |
|
trapezoid |
|
rhombus |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
A coordinate grid is composed of which of the following?
origin |
|
x-axis |
|
y-axis |
|
all of these |
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.

If angle a = 60° and angle b = 35° what is the length of angle d?
| 121° | |
| 150° | |
| 120° | |
| 118° |
An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite:
d° = b° + c°
To find angle c, remember that the sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 60° - 35° = 85°
So, d° = 35° + 85° = 120°
A shortcut to get this answer is to remember that angles around a line add up to 180°:
a° + d° = 180°
d° = 180° - a°
d° = 180° - 60° = 120°
