Use the protractor to measure this angle

You need to line the protractor up with the vertex first line area of the angle.

Or where possible zero or 180 should be at the start or end of the angle,

If this is a segment of a circle you can line horizontally and turn the page round count from the start of the angle or sometimes count from the end point. ie) if it shows 45 - 180 then 180-45 = 135

Pictures attached.

Step-by-step explanation:

Place either end of the protractor on the VERTEX of the angle.

Line up one side of the angle with the zero line of the protractor (where you see the number 0).

Read the degrees where the other side crosses the number scale.

you are saying it as if a fact, not a question, but yes, you would be correct? ; )
