A, B, and C are collinear and B is between A and C. Use the segment Addition Postulate to determine if AB = BC.
1. AB = 8, AC =18
2. AC = 18, BC = 9
3. AB = 12, AC = 24
4. BC = 15, AC = 20

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)
