Flashcard #1: Lessons 3.1 and 3.2_Part 1

Front

What is a tessellation?

Back

A tessellation is a pattern made of one or more shapes that fit together without any gaps or overlaps, covering a surface completely.

Front

What transformation is used to create a tessellation?

Back

Tessellations can be created using transformations such as translation, rotation, and reflection.

Front

Define translation in the context of transformations.

Back

Translation is a transformation that moves every point of a shape the same distance in a given direction.

Front

What is rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point, called the center of rotation, by a certain angle.

Front

What is reflection in geometry?

Back

Reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

How many lines of symmetry does a regular hexagon have?

Back

A regular hexagon has 6 lines of symmetry.

Front

What is line symmetry?

Back

Line symmetry occurs when a shape can be divided into two identical halves that are mirror images of each other.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a center point and still look the same at certain angles.

Front

How many degrees can a regular octagon be rotated onto itself?

Back

A regular octagon can be rotated onto itself at angles of 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees.

Front

What is the angle of rotation needed to map a regular octagon onto itself?

Back

The angle of rotation needed to map a regular octagon onto itself is 45 degrees.
