1) 10100,10200,10300,__________,10500.

The given sequence follows a pattern of increasing by 100 for each term. Starting with 10100, the next term is obtained by adding 100, resulting in 10200. This pattern continues until the missing term, which can be found by adding 100 to the previous term 10300, resulting in 10400. The sequence then continues with the next term being 10500.

2) Which one is a 3D shape?

Slate

CD

Chess board

Dice

Among the given options, dice is the only one that is a 3D shape. Slate, CD, and chess board are all flat objects and do not have a three-dimensional form. However, dice is a small cube-shaped object that has length, width, and height, making it a 3D shape.

3) Your image in the mirror is _____

Bigger

Smaller

Same size

None

When you look at yourself in a mirror, the image you see is the same size as your actual self. This is because mirrors reflect light in a way that preserves the proportions and size of the objects being reflected. Therefore, the image appears to be the same size as the object itself.

4) Cube has seven faces.

True

False

A cube actually has six faces, not seven. Each face of a cube is a square, and there are six squares in total, making up the six faces of the cube. Therefore, the correct answer is false.

5) In the following letters, which one forms the right angle?

L

K

Z

N

The letter "L" forms a right angle because it has one straight horizontal line and one straight vertical line that meet at a 90-degree angle.

Explanation

The letter "L" forms a right angle because it has one straight horizontal line and one straight vertical line that meet at a 90-degree angle.

6) Hand of a clock at 3.20 shows________

Right angle

Acute angle

Obtuse angle

Straight angle

The hand of a clock at 3.20 shows an acute angle. An acute angle is an angle that measures less than 90 degrees. Since the hand of the clock is pointing between the numbers 3 and 4, it forms an angle that is less than 90 degrees.

7) Three dimensions are length,width and _______

The three dimensions commonly used to describe the size or shape of an object are length, width, and height. Height refers to the vertical measurement or distance from the base to the top of an object. It is an essential dimension to fully define the size and shape of an object in three-dimensional space.

8) The circle has many lines of symmetry.

True

False

A circle has infinite lines of symmetry because any line passing through the center of the circle will divide it into two equal halves that are mirror images of each other. This means that no matter which direction the line is drawn, it will always create a line of symmetry. Therefore, the statement "The circle has many lines of symmetry" is true.

10) The height and slant height of the cone is equal.

True

False

The statement is false because the height and slant height of a cone are not equal. The height of a cone is the perpendicular distance from the base to the apex, while the slant height is the distance along the curved surface from the base to the apex. Since the slant height includes the curved surface, it is always longer than the height. Therefore, the height and slant height of a cone are not equal.
