How many lines of symmetry are there in a triangle?

Three Lines of Symmetry. An equilateral triangle has about three lines of symmetry. It is symmetrical along its three medians. Some other patterns also have three lines of symmetry. Four Lines of Symmetry. A square is symmetrical along four lines of symmetry, two along the diagonals and two along with the midpoints of the opposite sides.

Are there any letters that have zero lines of symmetry?

Right again! The Q, R, S are not symmetrical, so they have zero lines of symmetry. The T, U, and V are symmetrical, but they each have only one line of symmetry. None of these letters has two lines of symmetry.

How to find the symmetry of a shape?

Folding Test. You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry.

How many lines of symmetry are worth one point?

Based on the number of lines of symmetry a letter has, that’s how much the letter is “worth”. Letters with zero lines of symmetry are worth zero points. Letters with one line of symmetry are worth one point.
