Classwork
Examples1β4
1. Plotand connect the points π΄ (3, 2), π΅ (3, 7), and πΆ (8, 2). Name the shape and determine the area of the polygon.
2. Plotand connect the points πΈ (β8, 8), πΉ (β2, 5), and πΊ (β7, 2). Then give the best name for the polygon and

5. Two of the coordinates of a rectangle are π΄ (3, 7) and π΅ (3, 2). The rectanglehas an area of 30 squareunits. Give
the possiblelocationsof the other two vertices by identifyingtheir coordinates. (Use the coordinateplaneto draw
out and check your answer.)
