Example Questions
Example Question #1 :Squares, Rectangles, And Parallelograms
Note: Figure NOT drawn to scale
Refer to the above figure, which shows a rectangular garden (in green) surrounded by a dirt path (in brown) six feet wide throughout. What is the perimeter of thegarden?
The inner rectangle, which represents the garden, has length and width
Example Question #2 :Squares, Rectangles, And Parallelograms
Which of the following can be the sidelengths of a rhombus?
The four sides of a rhombus have equal length, so we can eliminate three choices by demonstrating that at least two sidelengths are not equal.
1,000 meters is, by definition, equal to 1 kilometer, not 0.1 kilometers. Therefore,
and this choice is incorrect.
1 mile is, by definition, equal to 5,280 feet, not 1,760 feet. Therefore,
and this choice is incorrect.
By definition, 1 decimeter, not 0.1 decimeter, is equal to 1 meter. Therefore,
and this choice is incorrect.
All four sides have equal length so this is the rhombus. This is the correct choice.
Example Question #3 :Squares, Rectangles, And Parallelograms
Identify the above polygon.
Pentagon
Rhombus
Hexagon
Trapezoid
Hexagon
A polygon with six sides is called a hexagon.
Example Question #1 :Perimeter And Sides Of Quadrilaterals
Refer to the above three figures. All parallel sides are so indicated.
Which of the figures can be called a quadrilateral?
Figures A and B only
Figures A, B, and C
Figures B and C only
Figure C only
Figures A, B, and C
By definition, any polygon with four sides is called a quadrilateral. All three figures fit this description.
Example Question #1261 :Ged Math
Refer to the above diagram. Parallel sides are so indicated.
Identify the above polygon.
Hexagon
Parallelogram
Trapezoid
Pentagon
Trapezoid
A four-sided figure, or quadrilateral, with one pair of parallel sides and its other sides nonparallel is called a trapezoid.
Example Question #6 :Squares, Rectangles, And Parallelograms
Refer to the above figure. You are given that
Which of the following words accurately describes Polygon
Hexagon
Parallelogram
Pentagon
Trapezoid
Trapezoid
Polygon
The quadrilateral has one pair of parallel sides, and the other two sides are not parallel. Therefore, it is a trapezoid.
Example Question #1 :Squares, Rectangles, And Parallelograms
Refer to the above three figures. All parallel sides are so indicated.
Which of the figures can be called a parallelogram?
Figures A and B only
Figure B only
Figures A, B, and C
Figure C only
Figures A and B only
A parallelogram, by definition, has two pairs of parallel sides. Figures A and B fit that criterion, but Figure C does not.
Example Question #8 :Squares, Rectangles, And Parallelograms
Note: Figure NOT drawn to scale.
Refer to the above figure, which shows a rectangular garden (in green) surrounded by a dirt path (in brown). The dirt path is
The length of the garden is
The width of the garden is
The perimeter is twice the sum of the two:
Example Question #9 :Squares, Rectangles, And Parallelograms
Note: Figure NOT drawn to scale.
Quadrilateral
The four sides of a rhombus are congruent. Also, the diagonals of a rhombus are perpendicular bisectors to each other, so the four triangles they form are right triangles. Therefore, the Pythagorean theorem can be used to determine the common sidelength of Quadrilateral
We focus on
By the Pythagorean Theorem,
13 is the common length of the four sides of Quadrilateral
Example Question #10 :Squares, Rectangles, And Parallelograms
Note: Figure NOT drawn to scale

Opposite sides of a rectangle are congruent, so
and

Opposite sides of a rectangle are congruent, so
and
The ratio of the perimeters is
