Question

define line of symtery​

Answer 1

Answer:

HOPE IT HELPS YOU..

Step-by-step explanation:

Reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry, is symmetry with respect to reflection. That is, a figure which does not change upon undergoing a reflection has reflectional symmetry. In 2D there is a line/axis of symmetry, in 3D a plane of symmetry.

Answer 2

Answer:

A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly. Equally, if you were to place a mirror along the line, the shape would remain unchanged.
