This is a game about Symmetry. The game creates a grid of triangles with two red lines (x and y-axis) in the centre of the display. The triangles are white but if we click them, they change color to blue and if we make click on it again change the color to white. At the start of the game we will see on display a pattern of some blue squares (two triangles blue) and we must complete the symmetric pattern with the x or y-axis as the line of symmetry. There are two situations in this game symmetric pattern with x-axis as the line of symmetry or symmetric pattern with y=axis as line of symmetry. We click on the appropriate triangles to create the symmetric pattern and if we make the right choices the game makes a check with automated way and we see a green sign if we answer right or a red sign in different situation. This is a useful teaching resource for Teachers, Parents and Students
