角的度量单位是度、分、秒,把一个平角180等分,每一份就是1度的角,1度记作1°;把1°的角60等分,每一份叫做1分的角,记作1′;把1′的角60等分,每一份叫做1秒的角,1秒记作1″.角的度量单位是六十进位,即1°=60′,1′=60″.关于角的度量和换算一直是同学们学习中的难点,下面通过几 The unit of measure for angles is degrees, minutes, and seconds. Divide a flat angle into 180 equal parts. Each is an angle of 1 degree, 1 degree is recorded as 1 degree, and 1 degree is divided into 60 equal parts. Each is called 1 point. The angle is denoted as 1′; divide the angle of 1′ into 60 equal parts, each part is called the angle of 1 second, 1 second is recorded as 1′′. The unit of measurement of the angle is the hexadecimal, ie 1°=60′, 1′ =60′′. On the measurement and conversion of the angle has been a difficult task for students to learn, the following
