If the base of this triangle is 1 and the height is 3, what is the area?
| 1\(\frac{1}{2}\) | |
| 38\(\frac{1}{2}\) | |
| 18 | |

The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 1 x 3 = \( \frac{3}{2} \) = 1\(\frac{1}{2}\)
A trapezoid is a quadrilateral with one set of __________ sides.
equal angle |
|
right angle |
|
parallel |
|
equal length |
A trapezoid is a quadrilateral with one set of parallel sides.
If a = c = 6, b = d = 5, what is the area of this rectangle?
| 30 | |
| 40 | |
| 7 | |
| 14 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 6 x 5
a = 30
Order the following types of angle from least number of degrees to most number of degrees.
right, acute, obtuse |
|
right, obtuse, acute |
|
acute, right, obtuse |
|
acute, obtuse, right |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
For this diagram, the Pythagorean theorem states that b2 = ?
c2 + a2 |
|
c2 - a2 |
|
c - a |
|
a2 - c2 |
The Pythagorean theorem defines the relationship between the side lengths of a right triangle. The length of the hypotenuse squared (c2) is equal to the sum of the two perpendicular sides squared (a2 + b2): c2 = a2 + b2 or, solved for c, \(c = \sqrt{a + b}\)
