There's the protractor, a bevel gauge, and the plain ol' measuring tape with pen and paper.
Inclinometer.
Protractors
A sextant.the sextonan astrolabe
Some of the devices used to measure angle are Transit, Protractor and Compass.
A protractor is commonly used on two-dimensional renderings.
The instrument used for measuring slope angles is called an inclinometer or clinometer. An inclinometer typically measures the angle of a slope relative to a horizontal plane, while a clinometer can also be used for measuring angles of elevation or depression. Both tools are essential in fields such as surveying, geology, and construction.

Some of the devices used to measure angle are Transit, Protractor and Compass.
A sextant measures the angle of elevation between the horizon and the north star. Along with charts, it can be used to calculate your position on the sea fairly accurately.
A protractor is commonly used on two-dimensional renderings.
the angle of elevation from L to K measures 55 degrees. If JK=26,find JL. roind to the nearest tenth
9.3
A protractor measures degrees: 90, 80, 120 etc. If something is 90 degrees it is at a right angle
universal bevel protactor is an angle measuring instrument which measures acute angle ,obtuse angle as well as it is used to layout an angle. its least count is 5 minute.
The instrument used for measuring slope angles is called an inclinometer or clinometer. An inclinometer typically measures the angle of a slope relative to a horizontal plane, while a clinometer can also be used for measuring angles of elevation or depression. Both tools are essential in fields such as surveying, geology, and construction.
Angle of elevation is looking upwards to an object and angle of depression is looking downwards to an object
