How many lines of symmetry does a triangle have? 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.
Explain to the student that a line of symmetry is an imaginary line that divides a figure into two congruent parts, each of which is the mirror image of the other. Provide the student with a mirror. Have the student use the mirror to determine if a line drawn is actually a line of symmetry. Provide additional practice through a symmetry sort. Provide the student with two-dimensional figures (some with lines of symmetry and some with lines drawn that are not lines of symmetry).
