Read the full guide
How an angle is written
∠A names an angle by its vertex. With three points the vertex goes in the middle, so ∠ABC is the angle at B. m∠A means its size, as in m∠A = 40°. The degree sign follows the number with no space, and minutes and seconds take primes, not quote marks: 30° 12′ 5″.
Tips
LaTeX's kernel builds \angle from a slash and a rule. Loading amssymb swaps in a real character, and adds \measuredangle and \sphericalangle.
A hat also marks an angle: \widehat{ABC} in LaTeX, or a letter plus the combining circumflex U+0302: the row A with a hat.
The raised g of 50ᵍ is the gradian, 1/100 of a right angle. Its standard symbol today is gon.
Questions and answers
Is there an Alt code for the angle symbol?
Not for ∠, and no Option key either. On a number pad the right angle ∟ is Alt+28 and the degree sign ° is Alt+248 or Alt+0176. On a Mac with the U.S. layout, ° is Option+Shift+8.
What is the HTML code for the angle symbol?
∠ or ∠ for ∠. The measured angle ∡ is ∡, the spherical angle ∢ is ∢, the right angle ∟ is ∟ and ° is °.
What is the symbol for a right angle?
∟, Right angle, U+221F. In a diagram a right angle is usually marked with a small square, which is ⦜. German-speaking countries and Poland use an arc with a dot, ⦝. ⟂ says two lines are perpendicular, and 90° or π/2 gives the size.
What is the difference between ∠, ∡ and ∢?
All three date from Unicode 1.1 (1993). ∠ is Angle, the plain sign of ∠ABC. ∡ is Measured angle, with an arc across it. ∢ is Spherical angle, which Unicode notes as angle arc. A size is written with the plain sign: m∠A.
∠AngleU+2220. The plain angle sign, written before the vertex or three points, as in ∠A or ∠ABC. No Alt code and no Option key; ∠ in HTML, \angle in LaTeX.
∠ABCAngle ABCMade of U+2220, U+0041, U+0042 and U+0043. The angle at B: the vertex is always the middle letter. Put your own letters in place of A, B and C.
°Degree signU+00B0. Follows the number with no space when it measures an angle, as in 30°. Alt+248 or Alt+0176 on a number pad, Option+Shift+8, Compose o o, ° in HTML, \textdegree in LaTeX.
θGreek small letter thetaU+03B8. One of the Greek letters commonly used to name an angle. No Alt code: Alt+233 types the capital. θ in HTML, \theta in LaTeX.
m∠AMeasure of angle AMade of U+006D, U+2220 and U+0041. The m in front says the size of the angle is meant, as in m∠A = 40°.
∡Measured angleU+2221. The angle sign with an arc across it. ∡ in HTML; \measuredangle in LaTeX needs the amssymb package.
