Test: Symmetry - 2 - Class 4 MCQ

A mirror reflection represents reflection symmetry. It means that one half of the object reflects the other half, just like a reflection in a mirror.

Glide symmetry combines translation and reflection transformations. It is a combination of sliding an object along an axis and reflecting it.

An equilateral triangle has three lines of symmetry. Each line passes through a vertex and bisects the opposite side.

A tree does not have symmetry. It is an example of an asymmetrical object, meaning it lacks balanced and proportionate similarity in its halves.

A shape that is not symmetrical is referred to as asymmetrical. It means that the shape does not have a mirror image or balanced halves.

The term used for the angle at which a figure can be rotated to coincide with itself is the order of symmetry. It represents the rotational property of the shape.

Rotational symmetry is observed when an object is rotated around a point and remains identical. It means that the shape can be rotated by a certain angle and still have the same appearance.

The letter X has two lines of symmetry. It can be folded vertically and horizontally, resulting in two mirror-image halves.

The combination of translation and reflection transformations is defined as glide symmetry. It involves both sliding an object along an axis and reflecting it.

Reflection symmetry is observed when both halves of an object mirror each other. It means that one half reflects the other half, resulting in a balanced and mirror-image appearance.
