1. What are the angles between two hands of a clock at 2 O' clock?

Right Angle

Acute angle

Obtuse Angle

Straight angle

At 2 O'clock, the minute hand is on the 12 and the hour hand is on the 2. The angle between the two hands is less than 90 degrees, which classifies it as an acute angle.

Explanation

At 2 O'clock, the minute hand is on the 12 and the hour hand is on the 2. The angle between the two hands is less than 90 degrees, which classifies it as an acute angle.

2. What kind of angle it is?

90 Degree angle

More than 92 degree angle

Less than 90 degree angle

180 degree angle

The given answer is "Less than 90 degree angle." This is because a 90-degree angle is a right angle, and the other options (more than 92 degrees and 180 degrees) are not less than 90 degrees.

Explanation

The given answer is "Less than 90 degree angle." This is because a 90-degree angle is a right angle, and the other options (more than 92 degrees and 180 degrees) are not less than 90 degrees.

3. An angle whose measure is between 0˚ and 90˚ is called an __________________ angle.

Obtuse Angle

Acute Angle

Right Angle

Straigth Angle

An angle whose measure is between 0˚ and 90˚ is called an acute angle.

Explanation

An angle whose measure is between 0˚ and 90˚ is called an acute angle.

4. What measure (in degrees) should be added to 34-degree angle to make a right angle?

55 degree

56 degree

66 degree

40 degree

To make a right angle, we need to add 90 degrees to the given 34-degree angle. Since the options provided are all greater than 90 degrees, we can eliminate 40 and 55 degrees as they would result in obtuse angles. The only option left is 56 degrees, which when added to 34 degrees, gives us a right angle of 90 degrees.

8. Which of the following statements is true about the sum of the interior angles of polygons?

The sum of the interior angles of any polygon is always 360 degrees.

The sum of the interior angles of a triangle is 180 degrees.

The sum of the interior angles of a quadrilateral is 180 degrees.

The sum of the interior angles of any polygon is directly proportional to the number of its sides.

The sum of the interior angles of a polygon can be found using the formula (�−2)×180(n−2)×180 degrees, where �n is the number of sides. For a triangle (�=3n=3), this sum is 180180 degrees. For a quadrilateral (�=4n=4), the sum is 360360 degrees. Therefore, option B is correct, indicating that the sum of the interior angles of a triangle is indeed 180 degrees.
