isosceles and right |
|
equilateral, isosceles and right |
|
equilateral and right |
|
equilateral and isosceles |
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
A trapezoid is a quadrilateral with one set of __________ sides.
equal length |
|
right angle |
|
equal angle |
|
parallel |
A trapezoid is a quadrilateral with one set of parallel sides.
Which of the following statements about a triangle is not true?
area = ½bh |
|
sum of interior angles = 180° |
|
perimeter = sum of side lengths |
|
exterior angle = sum of two adjacent interior angles |
A triangle is a three-sided polygon. It has three interior angles that add up to 180° (a + b + c = 180°). An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite (d = b + c). The perimeter of a triangle is equal to the sum of the lengths of its three sides, the height of a triangle is equal to the length from the base to the opposite vertex (angle) and the area equals one-half triangle base x height: a = ½ base x height.
If a = 8, b = 7, c = 8, and d = 7, what is the perimeter of this quadrilateral?
| 24 | |
| 30 | |
| 14 | |
| 20 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 8 + 7 + 8 + 7
p = 30
The dimensions of this cube are height (h) = 7, length (l) = 4, and width (w) = 2. What is the volume?
| 56 | |
| 729 | |
| 15 | |
| 96 |
The volume of a cube is height x length x width:
v = h x l x w
v = 7 x 4 x 2
v = 56
