Follow the steps to graph a face. 1 unit equals 1 pixel. A pixel is
a square dot on a computer screen.
1. Plot the polygon with vertices (-60, 100),
(-20, 20), and (-100, 20).
2. What is the name of the shape of the polygon?
3. What is the length of the horizontal line segment?
4. Plot a polygon in Quadrant I with vertices that are
reflections across the y-axis of the vertices of the
polygon in Quadrant II.
5. What are the vertices of the polygon in Quadrant l?
6. Plot the triangle with vertices (0, -30), (0, -110), and (-90, -70).
Do not draw a line segment between (0, -30) and (0, -110).
