On a coordinate grid, the location of a lighthouse is at L, Warm Up – 9/10/13 On a coordinate grid, the location of a lighthouse is at L, and the location of a buoy is at B. At noon, the buoy is the midpoint of the segment connecting a ship and the lighthouse on the grid. What are the coordinates that represent the ship’s position?

Angles on Parallel Lines

Corresponding (F) angles Corresponding Angles are EQUAL x x x x x x x x

Interior Angles add up to 180 Co Interior (C) angles Interior Angles add up to 180 a a a + b = 180 a + b =180 b b
