Geometry Terms Game

Geometry is the branch of mathematics that studies the sizes, shapes, positions, and dimensions of things. To understand it, we start with the simplest building blocks and move toward more complex relationships.

Geometry Terms Game
This game is a matching challenge designed to test your knowledge of fundamental geometric terms. It combines written definitions with visual hints to help you identify the correct terms. Scroll down the page for a more detailed explanation.

How to Play the Geometry Terms Game

Read the Definition
At the top of the screen, you will see a text definition (e.g., “Lines that meet or cross at a right angle”). This is your primary clue.
Look at the Visual Hint
Directly below the text is a visual representation of the term. These are simplified geometric drawings:
Select the Term
Choose the correct name from the grid of 6 options below.
Correct Choice: The card turns green, you gain 10 points, and a new question appears after a short delay.
Incorrect Choice: The card shakes and turns red. You can try again immediately until you find the right one.

The Geometry Terms used in this game are:
Parallel: Lines that are always the same distance apart and never touch.
Perpendicular: Lines that meet or cross at a right angle (90°).
Acute Angle: An angle that measures less than 90 degrees.
Obtuse Angle: An angle that measures more than 90 degrees but less than 180.
Vertex: A point where two or more lines, edges, or curves meet.
Ray: A line with one start point that goes on forever in one direction.
Segment: A part of a line that is bounded by two distinct end points.
Circumference: The distance around the outside of a circle.

The video gives a clear, step-by-step approach to learn geometry terms.
