Which clock’s hands show an right angle?
- A.
Clock C
- B.
Clock A
- C.
Clock B
Correct Answer
A. Clock CExplanation
Clock C is the correct answer because it is the only clock that has hands that form a right angle. The hour hand and minute hand of Clock C are positioned at 3 and 9 respectively, forming a right angle between them. Clock A and Clock B do not have their hands positioned in a way that forms a right angle.Rate this question:

What is the name for the figure below?
- A.
Obtuse
- B.
Right
- C.
Acute
Correct Answer
B. RightExplanation
The figure below is called a right angle. A right angle is formed when two lines or line segments meet at a 90-degree angle. In the given figure, the two lines meet at a 90-degree angle, making it a right angle.Rate this question:

Which angle has exactly 90 degrees?
- A.
Obtuse
- B.
Acute
- C.
Right
Correct Answer
C. RightExplanation
A right angle is the angle that measures exactly 90 degrees. It is formed when two lines intersect and create a square corner. In a right angle, one of the lines is perpendicular to the other, dividing the angle into two equal parts of 45 degrees each.Rate this question:

Which angle has less than 90 degrees?
- A.
Acute
- B.
Right
- C.
Obtuse
Correct Answer
A. AcuteExplanation
An acute angle is an angle that measures less than 90 degrees. It is smaller than a right angle (90 degrees) and an obtuse angle (greater than 90 degrees). Therefore, an acute angle is the correct answer because it is the only option that fulfills the condition of having less than 90 degrees.Rate this question:
