The right triangle in the image does not have any lines of symmetry as no line can divide it into two identical mirror-image halves. Therefore, the correct answer is 'none'.
The correct answer is "none".
A line of symmetry is a line that divides a shape into two identical halves, each being a mirror image of the other. The figure in the image is a right triangle. For this particular right triangle, there are no lines of symmetry. This is because no line can be drawn to divide the triangle into two identical halves where one half is the mirror image of the other. In general, different types of triangles have varying numbers of lines of symmetry; an equilateral triangle has 3, an isosceles has 1, and a scalene has none. Therefore, the correct answer to the question "How many lines of symmetry does the figure below have?" is 'none'.
