The present invention relates to a technology in respect to an angle measuring device which measures and marks angles. The purpose of the present invention is to solve a problem of an existing angle measuring device which cannot measure the inner and outer sides of an object structure of which the top and bottom are closed. The present invention includes two bar-plates of which each side is pivoted based on a scissors principle; gradations at a predetermined portion where the two bar-plates intersect and form an angle; and measurements which are formed on one side and which enables a user to know the measured value. Usually, angles are measured for mitering the measured angle and marking the angle on objects or building materials. Therefore, the angle measuring device with the two bar-plates of the present invention can measure an angle, marks the measured angle, and a mitting value, thereby enabling a user to cut an object and marks the measured angle on the object without an accurate angle or a separate calculation process. |
