So, what do u wanna solve?
your answers are correct
A straight angle measures 180°. It looks like a straight line with the vertex as a marked point on the line.
A right angle is usually marked with a little square in the corner, as in diagrams 2 and 5. Diagram 2 also shows complementary angles, two angles that have a sum of 90°.
Supplementary angles have a sum of 180°, so can form a straight angle as in diagram 1.
An obtuse angle is one that has a measure greater than 90°. (If it is greater than 180°, it is called a reflex angle.)
An acute angle is one that measures less than 90°.
I'm not sure if this is fully correct but I think it is.
