Angles Quiz For Grade III

The given angle is an obtuse angle because an obtuse angle is any angle that measures more than 90 degrees but less than 180 degrees. Since the question does not provide the specific measurement of the angle, we can only determine that it is obtuse based on the given options.

The given angle is a right angle because it measures exactly 90 degrees. In a right angle, one of the rays is perpendicular to the other, creating a 90-degree angle.

The given angle is a straight angle because it measures exactly 180 degrees. A straight angle forms a straight line, and all of its points lie on the same line.

An acute angle is an angle that measures less than 90 degrees. In the given question, the angle is not specified, but it is described as "acute." Therefore, the correct answer is "Acute" as it indicates that the angle is less than 90 degrees.

In a square, all four angles are right angles. This is because a square is a special type of quadrilateral where all sides are equal in length and all angles are equal to 90 degrees. Therefore, the correct answer is "Right".
