Example Question #12 : How To Find The Area Of A Parallelogram

What two shapes can a square be classified as? 

Possible Answers:

Trapezoid and Triangle 

Rhombus and Triangle 

Rectangle and Rhombus 

Trapezoid and Rhombus 

Rectangle and Triangle 

Correct answer:

Rectangle and Rhombus 

Explanation:

A square can also be a rectangle and a rhombus because a rectangle has to have at least  sets of equal side lengths and a rhombus has to have  equal side lengths, like a square, and at least  sets of equal angles.

Example Question #2 : Understand Categories And Subcategories Of Two Dimensional Figures: Ccss.Math.Content.5.G.B.3

What is the main difference between a triangle and a rectangle?

Possible Answers:

The volume

The length of the sides

The area

The color

The number of sides

Correct answer:

The number of sides

Explanation:

Out of the choices given, the only characteristic used to describe shapes is the number of sides. A triangle has  sides and a rectangle has  sides. 

Example Question #4 : How To Find The Area Of A Parallelogram

Which two shapes have to have  right angles? 

Possible Answers:

Rectangle and Parallelogram

Square and Rectangle 

Rectangle and Rhombus

Square and Parallelogram

Square and Rhombus

Correct answer:

Square and Rectangle 

Explanation:

By definition, the only two quadrilaterals that have to have  right angles, are the square and the rectangle. 

Example Question #5 : How To Find The Area Of A Parallelogram

Which of the shapes is NOT a quadrilateral? 

Possible Answers:

Square

Hexagon

Trapezoid

Rectangle 

Rhombus

Correct answer:

Hexagon

Explanation:

A quadrilateral is a  sided shape. The only shape listed that does not have  sides is a hexagon, which has  sides. 

Example Question #2 : Understand Categories And Subcategories Of Two Dimensional Figures: Ccss.Math.Content.5.G.B.3

Which of the following shapes is NOT a parallelogram? 

Possible Answers:

Kite

Square

Rhombus

Rectangle

Correct answer:

Kite

Explanation:

A rectangle, square, and rhombus can all be classified as a parallelogram because each shape has opposite side lengths that are equal. A kite does not. 

Example Question #3 : Understand Categories And Subcategories Of Two Dimensional Figures: Ccss.Math.Content.5.G.B.3

What is the difference between a trapezoid and a isosceles trapezoid? 

Possible Answers:

A trapezoid has to have equal base angles

An isosceles trapezoid has to have equal side lengths 

There is no difference between them 

An isosceles trapezoid has to have equal base angles

A trapezoid has to have equal side lengths 

Correct answer:

An isosceles trapezoid has to have equal base angles

Explanation:

By definition, an isosceles trapezoid has to have  equal base angles, but a trapezoid does not have to have equal angles. 

Example Question #8 : Shape Properties

Which shape is NOT a quadrilateral?

Possible Answers:

Circle

Kite

Rectangle 

Rhombus

Trapezoid

Correct answer:

Circle

Explanation:

A quadrilateral has to have  sides, a circle does not have any sides. 

Example Question #1 : How To Find If Right Triangles Are Similar

What is the main difference between a right triangle and an isosceles triangle? 

Possible Answers:

A right triangle has to have a  angle and an isosceles triangle has to have  equal, base angles. 

An isosceles triangle has to have a  angle and a right triangle has to have  equal, base angles. 

A right triangle has to have a  angle and an isosceles triangle has to have  equal, base angles. 

A right triangle has to have a  angle and an isosceles triangle has to have equal, base angles. 

A right triangle has to have a  angle and an isosceles triangle has to have  equal, base angles. 

Correct answer:

A right triangle has to have a  angle and an isosceles triangle has to have  equal, base angles. 

Explanation:

By definition, a right triangle has to have one right angle, or a  angle, and an isosceles triangle has  equal base angles and two equal side lengths. 

Example Question #1671 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

What is the difference between an equilateral triangle and a scalene triangle? 

Possible Answers:

The number of side lengths 

The length of their sides

The sum of their angle measurements

The sum of their side lengths 

Their color 

Correct answer:

The length of their sides

Explanation:

Of the choices listed, the main difference between an equilateral triangle and a scalene triangle is their side lengths. An equilateral triangle has to have  equal sides, but a scalene triangle can have all different side lengths. 

Example Question #11 : Shape Properties

A two-dimensional figure has four sides, the length is 3 centimeters. All of its four angles are right angles. Choose the correct category (or categories) that describes this type of figure.

Possible Answers:

All four categories are correct.

rectangle

square

quadrilateral

rhombus

Correct answer:

All four categories are correct.

Explanation:
