Elementary shapes are common, simple and regular shapes. They are the basic shapes in science. Prove how much you know about elementary shapes with this quiz.

Questions and Answers

1.

3D shapes can be formed from the combination of 2D shapes
- A.
  
  Yes
- B.
  
  No
- C.
  
  Maybe
- D.
  
  I`m not sure
Correct Answer
A. Yes

Explanation
3D shapes can indeed be formed by combining 2D shapes. This is because 3D shapes have volume and depth, which can be achieved by stacking or merging multiple 2D shapes together. For example, a cube can be formed by combining six square faces. Similarly, a cylinder can be formed by combining a rectangle and two circles. Therefore, the statement "3D shapes can be formed from the combination of 2D shapes" is correct.

Which shape has the most corner/edges?
- A.
  
  Triangle
- B.
  
  Circle
- C.
  
  Square
- D.
  
  Oval
Correct Answer
C. Square

Explanation
A square has four corners and four edges. Triangle has three corners and three edges. Circle has no corners and no edges. Oval has no corners and two curved edges. Therefore, the shape with the most corners/edges is a square.

A combined pairs of triangles can possibly make what shape?
- A.
  
  Oblongs
- B.
  
  Circles
- C.
  
  Triangles
- D.
  
  Squares
Correct Answer
D. Squares

Explanation
A combined pair of triangles can possibly make a square. By placing two congruent right triangles with their hypotenuses together, they form a square shape. Each triangle forms one of the four sides of the square, and when combined, they create a closed shape with four equal sides and four right angles. Therefore, squares are the possible shape that can be made by combining pairs of triangles.

A triangle is called "Equilateral" in what condition
- A.
  
  If the sides and angles are different
- B.
  
  If the sides and angles are equal
- C.
  
  If the sides are double the angle
- D.
  
  If the angles are double the sides
Correct Answer
B. If the sides and angles are equal

Explanation
An equilateral triangle is a triangle in which all three sides and all three angles are equal. This means that if the sides and angles of a triangle are equal, then it can be classified as an equilateral triangle.

What makes the difference between Square and Rectangle ?
- A.
  
  Square is made of Straight lines
- B.
  
  Rectangle has angle 90 at all the edges
- C.
  
  Square has four sides
- D.
  
  Rectangle has four equal sides
Correct Answer
D. Rectangle has four equal sides

Explanation
The given answer correctly explains that the main difference between a square and a rectangle is that a rectangle has four equal sides, while a square does not necessarily have all equal sides. This explanation highlights the key characteristic that distinguishes the two shapes.

What is the shape of a Cylinder's base?
- A.
  
  Triangle
- B.
  
  Square
- C.
  
  Rectangle
- D.
  
  Circle
Correct Answer
D. Circle

Explanation
A cylinder's base is in the shape of a circle because a cylinder is a three-dimensional shape that consists of two parallel circular bases connected by a curved surface. The circular base provides a stable foundation for the cylinder and allows it to roll smoothly.

What shape possesses 3 sides?
- A.
  
  Square
- B.
  
  Triangle
- C.
  
  Oval
- D.
  
  Rectangle
Correct Answer
B. Triangle

Explanation
A triangle is a shape that possesses 3 sides. It is a polygon with three straight sides and three angles. Unlike a square or rectangle, which have 4 sides, and an oval, which has a curved shape, a triangle specifically refers to a shape with 3 sides.

What shape has a set of two parallel lines as its sides
- A.
  
  Rhombus
- B.
  
  Trapezium
- C.
  
  Kite
- D.
  
  Parallelogram
Correct Answer
D. Parallelogram

Explanation
A parallelogram has a set of two parallel lines as its sides. In a parallelogram, opposite sides are parallel and equal in length. Therefore, it fits the description given in the question. A rhombus also has two pairs of parallel sides, but all sides of a rhombus are equal in length, which is not specified in the question. A trapezium has only one pair of parallel sides, and a kite does not have any parallel sides.

A cube is made up of what shape?
- A.
  
  Circles
- B.
  
  Rectangles
- C.
  
  Squares
- D.
  
  Parallelograms
Correct Answer
C. Squares

Explanation
A cube is made up of squares because all six faces of a cube are identical squares. Each side of a square is equal in length, and when these squares are connected at their edges, they form a three-dimensional shape with equal length, width, and height, known as a cube.

Shapes more than 4sides and angles are caled what?
- A.
  
  Equilaterals
- B.
  
  Quadrilaterals
- C.
  
  Polygons
- D.
  
  Irregular Shapes
Correct Answer
C. Polygons

Explanation
Polygons are shapes that have more than four sides and angles. They are formed by connecting straight line segments to create a closed figure. Examples of polygons include triangles, quadrilaterals, pentagons, hexagons, and so on. Therefore, the correct answer is "Polygons."
