About This Quiz

As a part of mathematics, we all have studied geometry, haven't we? That's why we have come up with the 7th grade geometry trivia quiz for you. Geometry is, with arithmetic, known as one of the oldest branches of mathematics. It deals with properties of space like the distance, shape, size, as well as relative position of figures. These are some trivia questions that aren't going to be very difficult but fun and useful to answer. So, let's give them a try.

    • Circle

    • Triangle

    • Pentagon

    • Hexagon

    Correct Answer
    A. Circle
    Explanation
    The radius of a circle is the distance from the center of the circle to any point on its circumference.

    • 3

    • 7

    • 8

    • 9

    Correct Answer

  • 4. 

    Another word for 'slide' is

    • Rotation

    • Reflection

    • Translation

    • None of these

    Correct Answer
    A. Translation
    Explanation
    The word 'slide' refers to the movement of an object in a straight line without any rotation or reflection. Translation is the correct answer because it means shifting or moving something in a straight line without changing its orientation. Rotation involves turning or spinning an object around a fixed point, while reflection is the flipping of an object over a line. Therefore, neither rotation nor reflection can be considered as synonyms for 'slide'.

    Rate this question:

  • 5. 

    A pentagon has ________ sides.

    • 4

    • 5

    • 6

    • 7

    Correct Answer
    A. 5
    Explanation
    A pentagon has five sides. A pentagon is a polygon with five straight sides and five angles. The prefix "penta" means five, so a pentagon is specifically defined as having five sides.

    Rate this question:

  • 6. 

    A hexagon has ________ sides.

    • 4

    • 5

    • 6

    • 7

    Correct Answer
    A. 6
    Explanation
    A hexagon is a polygon with six sides.

    Rate this question:

  • 7. 

    A triangle has three sides with the total _______ angle.

    • 20 degree

    • 45 degree

    • 90 degree

    • 180 degree

    Correct Answer
    A. 180 degree
    Explanation
    A triangle has three sides, and the sum of the interior angles of a triangle is always 180 degrees. Therefore, the correct answer is 180 degrees.

    Rate this question:

  • 8. 

    Another word for 'flip' is

    • Rotation

    • Reflection

    • Translation

    • None of these

    Correct Answer
    A. Reflection
    Explanation
    The correct answer is "Reflection" because flipping refers to the action of reversing or inverting an object along a line, which is exactly what reflection means. Rotation refers to the act of turning or spinning an object around a fixed point, while translation refers to the process of moving an object from one place to another. Therefore, neither rotation nor translation can be considered as synonyms for "flip".

    Rate this question:

  • 9. 

    After a reflection, the image of X(3,4) is X’(-3,4).  Therefore, the line of reflection is

    • The x-axis

    • The y-axis

    • Over x=1

    • Over y=1

    Correct Answer
    A. The y-axis
    Explanation
    After reflecting the point X(3,4) to X'(-3,4), we can observe that the x-coordinate of the point remains the same while the y-coordinate changes its sign. This indicates that the reflection is happening along the y-axis, which acts as a mirror. Therefore, the correct answer is the y-axis.

    Rate this question:

  • 10. 

    Identify the coordinates of N’ if N(2,-1) is reflected through the x-axis

    • (2, 1)

    • (-2, -1)

    • (-2, 1)

    • (1, 2)

    Correct Answer
    A. (2, 1)
    Explanation
    When a point is reflected through the x-axis, the y-coordinate changes sign while the x-coordinate remains the same. In this case, the y-coordinate of N is -1, so when it is reflected through the x-axis, the sign of -1 changes to positive, resulting in a y-coordinate of 1. The x-coordinate remains 2. Therefore, the coordinates of N' are (2, 1).
