Question 1

Regular tessellation

Answer 1

a repeating pattern of congruent regular polygons that completely covers a plane with no gaps or overlaps.

Question 2

Rotational symmetry

Answer 2

A figure that can be rotated about a point by an angle less than 360 degrees, so that the image coincides with the preimage , has rotational symmetry

Question 3

Semiregular Tessellation

Answer 3

A repeating pattern formed by two or more regular polygons in which the same number of each polygon occur in the same order at every vertex, and completely cover a plane with no gaps or overlays.

Question 4

Symmetry

Answer 4

The transformation of a figure such that the image coincides with the preimage

Question 5

Tessellation

Answer 5

A repeating pattern of plane figures that completely covers a plane with no gaps or overlaps.

Question 6

Translation Symmetry

Answer 6

A figure has translation symmetry if it can be translated along a vector so that the image coincides with the preimage.
