welcome to math with Mr Jay in this video I'm going to go through quick review of five different types of angles let's jump into number one where we have an angle that measures 27 degrees so this is an example of an acute angle acute angles are less than 90 degrees let's move on to number two where we have an angle that measures 143 degrees this is an example of an obtuse angle obtuse angles are greater than 90 degrees and less than 180 degrees so again this is an example of an obtuse angle let's move on to number three where we have an angle that measures exactly 180 degrees this is called straight angle so any time an angle measures exactly 180 degrees it's called straight angle let's move on to number four where we have an angle that measures 298 degrees this is an example of reflex angle reflex angles are greater than 180 degrees and less than 360 Degrees 360 degrees is full rotation it creates full circle so again greater than 180 degrees and less than 360 degrees and then lastly we have an angle that is exactly 90 degrees this is called right angle now this square right here tells us that we have 90 degree angle it's common just to see square in the corner of 90 degree angle without the number 90 written so that's something to be aware of whenever you see that square it's 90 degree angle so there you have it there's quick review of five different types of angles hope that helped thanks so much for watching until next time peace foreign
