To Create A Complex Polygon With Given Side Lengths.

A polygon has 8 sides: five of length 1, two of length 2, and one of length 3. All sides lie on grid lines. Create a polygon with these properties.

Is there a second polygon, not congruent to your first, with these properties?

To Demonstrate that two Polygons are Congruent.

(1). Show that the two pentagons are congruent.

(2). Explain how you know that the two figures are congruent.

(3). Find the side lengths of ABCDE and the angle measures of FGHIJ.
