A right triangle either has one or no lines of symmetry. An isosceles right triangle, one with two sides of equal length, has one line of symmetry. A scalene right triangle, one with no sides of equal length, has no line...

The number of lines of symmetry a triangle has depends on the type of triangle. An equilateral triangle has three lines of symmetry, while an isosceles has one line of symmetry, and a scalene triangle has none.

An equilateral triangle has three lines of symmetry. There are three sides of equal length in an equilateral triangle. A line of symmetry is a line such that if a mirror is placed along it, its reflection appears identic...

A regular heptagon has seven lines of symmetry. Each one runs from a vertex to the opposite side, bisecting the side at a 90-degree angle.

Some shapes that have no lines of symmetry include the scalene triangle and trapezium. A trapezium is a four-sided flat shape with straight sides, none of which are parallel. Outside of the United States, the trapezium i...
