The coordinates of the turning point and the equation of the line of symmetry can be found by writing the quadratic expression in completed square form.

Find the equation of the line of symmetry and the coordinates of the turning point of the graph of y = x 2 6 x + 4 The coefficient of x 2 is positive, so the graph will be a positive U-shaped curve.

Peg uses a magic ukulele to find the line of symmetry on shapes.

A symmetry requires that the transformation not alter the size or shape of the object. A transformation that meets this requirement is known as an “isometry,” or a rigid motion, and the fundamental ...
