How many lines of symmetry does this figure have?  

The scalene triangle has no lines of symmetry.

Step-by-step explanation:

We can see that the given figure is a scalene right triangle.

A line of symmetry is a line that divides a figure into two mirror image halves. The line around which a figure is reflected over is called a line of symmetry.

The scalene triangle has no lines of symmetry. A scalene triangle is one which has no sides equal and no angles equal.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
