The figures pictured below are ________________________________________. They are closed, plane figures composed of segments that intersect only at their endpoints.

vertices

("vertices" is the plural of "vertex.")

Points W, F, S, U and Y are ________________________________________ of polygon WFSUY.

In the diagram below, segment AC is a(n) ________________________________________ of pentagon ABCDE.

Draw a kite shaped polygon on your paper somewhere. Notice that if you draw a segment connecting any two non-adjacent vertices that the segment only passes through the interior. We would classify the kite as a(n) ______________________________.

If you connect points O and Y on the figure below with a line segment, the segment will pass through the exterior of POLY. For that reason, we would classify POLY as a(n) ______________________________.

Based on the marks made on the diagram below, pentagon ABCDE is both equilateral and ______________________________.

In pentagon TIGER, TI = IG = GE = ER = RT. TIGER is a(n) ______________________________.

All 12 of a dodecagon’s sides are 10 centimeters long and each of its interior angles measures 150°. That makes it a(n) ________________________________________ dodecagon.

If you find the point that is the same distance from every vertex of a regular polygon, you have found the ______________________________ of that regular polygon.

In the figure below. If you were to draw ray FB and ray FA, the two rays would form a(n) ______________________________ of pentagon ABCDE.

Draw a triangle somewhere on a piece of scratch paper. Now, draw a point on one vertex of the triangle and draw rays that start at that vertex and pass through the sides of the triangle that meet at that vertex. These rays form a(n) ________________________________________ of the polygon you drew.

Because adjacent angles HAR and RAY are supplementary, we would classify angle HAR as a(n) ________________________________________ of ARLEY.

Trapezoids, parallelograms, rectangles, rhombuses, squares and kites are all examples of ________________________________________. That is, they are all four-sided polygons.

Based solely on the number of sides it has, ______________________________ is the name we would give to the polygon picture below:

[image]

The figure below is a(n) ______________________________. It is a six-sided polygon.

When we don’t know the number of sides of a polygon or when we are trying to prove a property that applies to a polygon regardless of the number of sides it has, we say that the polygon has n sides, and we refer to it as a(n) ______________________________.

A stop sign is a real-world example of a regular eight-sided polygon, which we call a regular ______________________________.

“Hepta” is a Greek prefix for “seven.” That’s why we call a seven sided polygon a(n) ______________________________.
