At 265°, this is a reflex angle, which goes more than halfway around a circle. It is the "outside" of a 95° angle: together they make a full 360° circle.
265° is 53/72 of a full circle, or 53π/36 radians. If you face north and turn 265° clockwise, you end up facing between WSW and W (closest to west (W)).

265° on a protractor
How to draw a 265° angle with a protractor
- Subtract from 360°: 360° − 265° = 95°. 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 95°.
- Join the vertex to the dot. The inside angle is 95°; the outside angle, going the long way around, is 265°. Draw the angle arc on the outside and label it 265°.
- With a 360° protractor you can skip the subtraction: put 0° on your first line and mark 265° directly.
Drawing it a 265° angle without a protractor (rise and run method)
- 265° = 180° − 85°. Draw a straight line, pick a vertex on it, and build an 85° angle on one side as follows; the angle on the other side of the new line is 95°.
- Draw a straight baseline and measure 0.87 inches (about 7/8″) along it from the vertex.
- At that mark, draw a line straight up at 90° and measure exactly 10 inches up it.
- Join the top mark to the vertex. The angle at the vertex is 85°, because tan 85° ≈ 11.4301.
- That gives you 95°. The outside (reflex) angle is 265°.
Where you see 265° angles
- The Earth turns 265° on its axis in about 17 h 40 min.
- A 265° 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.

265° angle FAQ
What type of angle is 265°?
A 265° angle is a reflex angle, because it is between 180° and 360°.
Does a 265° angle have a complement or supplement?
No. Complements add up to 90° and supplements to 180°, and 265° is already larger than both. What it does have is an explement (conjugate) of 95°, the angle that completes a full 360° circle.
How many radians is 265 degrees?
265° = 53π/36 radians ≈ 4.6251 rad. To convert degrees to radians, multiply by π/180: 265 × π/180 = 53π/36.
How do I measure a 265° angle on my screen?
Open the online protractor with 265° preset, or type 265 into its "Type an angle" box. You can then drag the arms onto your own lines to compare.
