Line up the vertex, then if it is an acute angle use the small number, obtuse use the big number, next all you have to do is bring your finger up to where the angle line is and see what number, big or small it lines up with on the protractor!
Use a protractor and the 4 interior angles should add up to 360 degrees.

put the protractor on the vertex and look up at the degree's and look belowacute angle =has a measure between 0 degree's and 90 degree'sright angle =has a measure of 90 degree'sobtuse angle = has a measure between 90 degree's and 180 degree'sstraight angle = has a measure of 180 degree'sthat's how you use a protractor to measure angles.
For a simple square or rectangle, you can draw four 90° angles (the corners) and connect them. The sum of the angles in any convex quadrilateral is 360°, so you can use other configurations to make parallelograms, for example.
it depends on the angle. Right angles always have 90 degrees. You can use a protractor to measure the angle
If you are given a picture of a triangle and no information about it, then you could use a protractor.
