A 356° angle is reflex because it measures between 180° and 360°. It is the "outside" of a 4° angle: together they make a full 360° circle.
356° is 89/90 of a full circle, or 89π/45 radians. If you face north and turn 356° clockwise, you end up facing between NNW and N (closest to north (N)).

356° on a protractor
How to draw a 356° angle with a protractor
- Subtract from 360°: 360° − 356° = 4°. A standard protractor only goes to 180°, so you draw the smaller angle first.
- Draw a straight line with a ruler and mark the vertex at one end.
- Place the protractor's center mark on the vertex, line up the 0° baseline with your line, and make a dot at 4°.
- Join the vertex to the dot. The inside angle is 4°; the outside angle, going the long way around, is 356°. Draw the angle arc on the outside and label it 356°.
- With a 360° protractor you can skip the subtraction: put 0° on your first line and mark 356° directly.
Drawing it a 356° angle without a protractor (rise and run method)
- Draw a straight baseline and measure exactly 10 inches along it from the vertex.
- At the 10-inch mark, draw a short line straight up at 90° (use a carpenter's square or the corner of a sheet of paper).
- Measure 0.7 inches (about 11/16″) up that line and make a mark.
- Join the mark to the vertex. The angle at the vertex is 4°, because tan 4° ≈ 0.0699.
- That gives you 4°. The outside (reflex) angle is 356°.
Where you see 356° angles
- The Earth turns 356° on its axis in about 23 h 44 min.
- A 356° reflex angle is what you measure when you go the "long way" around, like the outside corner of a building or a turn of more than half a circle.

356° angle FAQ
What type of angle is 356°?
A 356° angle is a reflex angle, because it is between 180° and 360°.
Does a 356° angle have a complement or supplement?
No. Complements add up to 90° and supplements to 180°, and 356° is already larger than both. What it does have is an explement (conjugate) of 4°, the angle that completes a full 360° circle.
How many radians is 356 degrees?
356° = 89π/45 radians ≈ 6.2134 rad. To convert degrees to radians, multiply by π/180: 356 × π/180 = 89π/45.
How do I measure a 356° angle on my screen?
Open the online protractor with 356° preset, or type 356 into its "Type an angle" box. You can then drag the arms onto your own lines to compare.
