Polygons

100

Which can have curved sides and intersecting lines a polygon or a non-polygon?

A non-polygon.

200

Irregular polygons have all congruent sides and angles. True of false?

False. Regular polygons have all congruent sides and angles. For example a square has 4, 90 degree angles and all of the sides lengths are equal.

300

Name five polygons.

Answers will vary. (examples: triangle, any quadrilaterals, Etc.)

Defining Angles

100

Explain complementary vs. supplementary.

Complementary angles add to 90 degrees whereas supplementary angles add to 180 degrees or a straight line.

200

Define adjacent angles.

Something close to: Two angles in a plane that share a common vertex and a common side but don't overlap. such as:

300

Contrast exterior angles and interior angles. Then tell how you can find the measure of an interior angles of a regular polygon.

Interior angles are on the inside of a polygon and can add to multiple numbers. Whereas the exterior angles are on the outside of a polygon and the sum of the exterior angles of any n-gon is 360 degrees.

What is reflection symmetry vs. rotational symmetry

Reflection symmetry is something that happens to a shape when it undergoes mirroring and does not change, for example a square. Whereas rotational symmetry happens when a figure can be turned from a center point and when turned at an angle does not change. for example a regular hexagon.

200

What are parallel lines.

two lines that could be extended is either way but never touch.

300

What is tessellation or tiling.

It is placing a shape on a plane over and over again and having there be no gaps in between the shapes. To do this you can use both rotation or reflection.
