- it has no reflectional symmetry.
- it has reflectional symmetry with one line of symmetry.
- it has point symmetry.
- it has rotational symmetry with an angle of rotation of 90 degrees.

Icould really use some with this question.

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Solve each quadratic equation by factoring and using the zero product property. n^2 - 49 = 0
