Determine the type of the angle highlighted in orange.
The question is asking us to think about the angle, which is highlighted in orange. We have to work out which type of angle it is. We need to think about the three different types of angle that this angle could be. Is it a right angle? Right angles measure exactly 90 degrees. It could be an acute angle, which is an angle which measures less than 90 degrees. It could also be an obtuse angle. Obtuse angles are angles which are greater than 90 degrees, but less than 180 degrees. Which of these three angles is our angle? Our angle measures less than 90 degrees.
The type of the angle highlighted in orange is an acute angle. This is an angle which measures less than 90 degrees.
