UNICOOL 16'5" X 16'5" X 22'11" Right Triangle Sun Shade Sail UV Block for Outdoor Garden Patio Sunscreen Awning Canopy Blue

Have used these in the past for over patio and pool areas, and they are great and inexpensive for shade! Can't say the same for this one. Make certain you verify the size and shape you need This one ended up being bigger than expected and the shape was NOT a triangle. Ended up being extremely awkward. The good news is, it wasn't expensive so we trashed it.

Not a right angle triangle. No 90 degree corner at all.Looks like an equilateral triangle to me.Math is hard.
