Warm Up Week 1

Section 6.1 Day 1 I will identify, name, and describe polygons. Ex 1 PolygonHas three or more sides that connect at endpoints (vertices) that are not collinear. Each side intersects with exactly two other sides.

Section 6.1 Day 1 I will identify, name, and describe polygons. Ex 1 PolygonHas three or more sides that connect at endpoints (vertices) that are not collinear. Each side intersects with exactly two other sides. Vertex Side

Ex 2 yes no D) Because one side is not a segment. E) Because two sides do not intersect at endpoints. F) Because some sides intersect with more than two sides. A, B, and C are polygons because they have at least 3 sides that connect at endpoints.
