Which of the following statements about a parallelogram is not true?
opposite sides and adjacent angles are equal |
|
a parallelogram is a quadrilateral |
|
the area of a parallelogram is base x height |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
If angle a = 51° and angle b = 69° what is the length of angle c?
| 60° | |
| 66° | |
| 65° | |
| 90° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 51° - 69° = 60°
A trapezoid is a quadrilateral with one set of __________ sides.
equal angle |
|
parallel |
|
equal length |
|
right angle |
A trapezoid is a quadrilateral with one set of parallel sides.
Simplify (9a)(4ab) - (4a2)(2b).

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
(9a)(4ab) - (4a2)(2b)
(9 x 4)(a x a x b) - (4 x 2)(a2 x b)
(36)(a1+1 x b) - (8)(a2b)
36a2b - 8a2b
28a2b

Inside |
|
First |
|
Last |
|
Odd |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
