Tessellations and Polygon Angles

The video tutorial explains tessellations, focusing on how shapes fit together without gaps. It begins with an introduction to tessellations using animal patterns, then explores hexagon tessellations, highlighting the importance of angles adding up to 360 degrees for perfect fitting. Finally, it examines tessellations involving octagons and squares, demonstrating angle calculations to ensure seamless fitting.

What is a tessellation?

• A type of painting technique

• A pattern made of shapes that fit together without gaps

• A method of solving equations

• A way to measure angles

Which of the following is an example of a tessellation?

• A single triangle

• A group of overlapping circles

• A random arrangement of squares

• A pattern of hexagons fitting together

Which city is mentioned in relation to a hexagon tessellation example?

• They must be regular polygons

• They must be colorful

What is the significance of the number 360 in tessellations?

• It is the total angle sum at a point in a tessellation

• It is the number of sides in a hexagon

• It is the number of colors used in a tessellation

• It is the number of shapes in a tessellation

What is the angle measure of each angle in a regular hexagon tessellation?

• 150 degrees

• 135 degrees

• 120 degrees
