Sprinkler Angles in the Community Garden

Add and subtract angle measures to water every plant.

Sprays side by side

Each sprinkler sprays water in the shape of an angle. When two sprays sit side by side with no gaps and no overlaps, add the parts to find the whole angle.

Two sprinklers water the tomato patch from the same spot. One sprays 45°. The other sprays 70°.

Together the two sprays cover °.

Jada puts a protractor on two sprays that sit side by side. Read the protractor to find each part and the whole angle.
