Question

Which of the marked angles is an acute angle?

• A. Image 2
• B. Image 3
• C. Image 1 and 3
• D. Image 1

Answer 1

The correct option is C Image 1 and 3

● The angle formed in image 2 bends backward and is more than a right angle.
● Hence, image 2 forms an obtuse angle.
● The angles formed in images 1 and 3 bend forward and are less than a right angle.
● Hence, the angles formed in images 1 and 3 are acute angles.
