Questions 1 - 10
1

Identify all of the different shapes that make up the following figure of a three-dimensional open box.

Open box

Rectangular Prism, Rectangle

Cube, Rectangle

Cube

Rectangular Prism, Cube

None of the other answers

Explanation

In the world around us, all figures can be looked at in geometric shapes.

Looking at the three-dimensional open box,

Open box

two figure can be broken down into two main shapes, one which is a three-dimensional shape and the other is a two-dimensional shape. The box itself can be described as a rectangular prism. The lid of the box, which is up and thus making the box open is a rectangle.

2

Identify all of the different shapes that make up the following figure of a two-dimensional stop light.

Stoplight

Rectangle, Circle

Rectangle, Trapezoid

Rectangle, Triangle

Square, Circle

None of the other answers

Explanation

In the world around us, all figures can be looked at in geometric shapes.

Looking at the two-dimensional stop light,

Stoplight

the figure can be broken down into two geometric shapes. The outside portion of the stop light is a rectangle and the lights are in the form of circles.

3

Identify all of the different shapes that make up the following figure of a two-dimensional flagpole.

Flagpole

Rectangle, Triangle

Square, Triangle

Rectangle, Trapezoid

Square, Trapezoid

None of the other answers

Explanation

In the world around us, all figures can be looked at in geometric shapes.

Looking at the two-dimensional flagpole,

Flagpole

the flagpole can be broken down into two geometric shapes. The pole portion of the flagpole can be described as a rectangle and the flag is in the shape of a triangle.

4

Objects in the real world can be described in geometric shapes. What geometric shape describes a water silo?

Cylinder

Sphere

Rectangle Prism

Triangle Prism

None of the other answers

Explanation

In the three-dimensional world a water silo has a bottom and top in the shape of a circle. The three-dimensional connection between the top and the bottom creates a cylinder. Therefore, the geometric shape that best describes the silo is a cylinder.

5

Objects in the real world can be described in geometric shapes. What geometric shape describes a basketball?

Sphere

Cylinder

Rectangle

Circle

Circular Prism

Explanation

A basketball is a three-dimensional object that when cut down the middle has a circular base. The geometric shape that describes a basketball is known as a sphere.

6

Sally orders a pair of shoes from an online store. The box that the shoes arrived in can be described as what geometric shape?

Rectangular Prism

Sphere

Cylinder

Triangular Prism

None of the others.

Explanation

A box in three-dimensional space can be describes as either a cube or a rectangular prism depending on the side lengths. Since rectangular prism is the only option available, this is the best option. Most shoe boxes in general are rectangular prisms since shoes are longer than they are wide.

7

Identify all of the different shapes that make up the following figure of a two-dimensional snowman.

Snowman

Circle, Line

Circle

Line

Oval, Triangle

None of the other answers.

Explanation

In the world around us, all figures can be looked at in geometric shapes.

Looking at the two-dimensional snowman,

Snowman

the figure can be broken down into one main geometric shape, a circle. The base, torso, and head of the snowman are all circles and the arms are lines. Therefore, the geometric shapes of the two-dimensional snowman are circles and lines.

8

Identify all of the different shapes that make up the following figure of a two-dimensional non traditional stop sign.

Stopsign

Hexagon, Rectangle

Octagon, Rectangle

Hexagon, Octagon

Rectangle, Square

None of the other answers

Explanation

In the world around us, all figures can be looked at in geometric shapes.

Looking at the two-dimensional non traditional stop sign,

Stopsign

the figure can be broken down into two geometric shapes. It is important to point out that this stop sign is a non traditional one. Normal stop signs are octagons which have eight sides. This particular stop side only has six sides and is therefore a hexagon. Therefore, this non traditional stop sign can be broken down into a hexagon and a rectangle.

9

Objects in the real world can be described in geometric shapes. What geometric shape describes a coffee mug without a handle?

Open Cylinder

Prism

Rectangle Prism

Sphere

None of the other answers.

Explanation

In the three-dimensional world a coffee mug without a handle has a bottom and top in the shape of a circle. The three-dimensional connection between the top and the bottom creates a cylinder. Therefore, the geometric shape that best describes the coffee mug is an open cylinder since there is no top on the coffee mug.

10

Identify all of the different shapes that make up the following figure of a two-dimensional wagon.

Wagon

Rectangle, Circle, Quadrilateral

Rectangle, Circle

Parallelogram, Rectangle

Circle, Square, Parallelogram

None of the answers

Explanation

In the world around us, all figures can be looked at in geometric shapes.

Looking at the following two-dimensional wagon,

Wagon

the figure can be broken down into three different shapes. The body of the wagon is a rectangle, the wheels are seen geometrically as circles and the handle is a quadrilateral.

Recall that to be a square, the quadrilateral has to have four equal side lengths.

A parallelogram must have opposite parallel sides, this particular figure doesn't give enough information to determine whether the handle is a parallelogram.

A quadrilateral is a more correct statement as it describes a figure with four sides.

Therefore, the correct answer is, "Rectangle, Circle, Quadrilateral".
