Which statement about mirror and water images is correct?
Answer: A
Mirror reflection is a horizontal flip (left-right reversal), while water reflection is a vertical flip (top-bottom reversal). This is the fundamental difference.
Q.42Easy
A rectangular shape with width 4cm and height 6cm appears in a mirror. What are its dimensions in the mirror image?
Answer: C
Mirror image doesn't change the actual dimensions of a figure, only reverses its orientation horizontally. The size remains 4cm × 6cm.
Q.43Easy
A digital display shows '88'. What will it show in a mirror image?
Answer: A
The digit '8' is symmetrical both horizontally and vertically. Therefore, '88' appears the same in mirror image.
Q.44Easy
Which number remains unchanged when reflected in a mirror?
Answer: A
Numbers 1, 8, and 0 are symmetrical horizontally. They appear the same in mirror image. Other digits change their appearance.
Q.45Easy
What is the mirror image of the letter 'b'?
Answer: A
When 'b' is reflected horizontally in a mirror, it becomes 'd' as the bulge shifts from right to left.

Q.46Easy
Which of the following letters has vertical line symmetry in both mirror and water images?
Answer: A
The letter 'A' has vertical axis symmetry, so it appears identical in both mirror and water images.
Q.47Easy
In a mirror image, if the angle between two lines is 60 degrees, what will be the angle in the mirror image?
Answer: B
Angles remain unchanged in mirror images. The 60-degree angle stays 60 degrees because angles are geometric properties preserved in reflection.
Q.48Easy
A right-angled triangle has its right angle at the bottom-left corner. When reflected in a vertical mirror, where will the right angle appear?
Answer: A
Vertical mirror reflection (left-right reversal) moves the right angle from bottom-left to bottom-right.
Q.49Easy
In a water image of a geometric figure, if a point moves 3cm upward from the centerline, where will it appear in the water image?
Answer: B
Water image involves horizontal mirror reflection. Vertical positions are inverted, so 3cm upward becomes 3cm downward.
Q.50Easy
In a water image (horizontal mirror), the arrangement '5 3 8 1' becomes:
Answer: A
Water image involves horizontal reflection, reversing the order of elements. '5 3 8 1' becomes '1 8 3 5' when reflected horizontally.
Q.51Easy
Which of the following symbols has both vertical and horizontal symmetry?
Answer: A
The symbol ⊕ (circle with cross) has both vertical and horizontal line symmetry. Triangle has only vertical, diamond has both diagonals but the question refers to perpendicular axes, and arrow has neither.
Q.52Easy
In water image transformation, a right-pointing arrow '→' becomes:
Answer: A
Water image (horizontal reflection) reverses left-right orientation. A right-pointing arrow becomes left-pointing arrow.
Q.53Easy
Which digit from 0-9 looks identical to its mirror image when reflected in a vertical mirror?
Answer: A
Digits 0, 1, and 8 have vertical line symmetry and appear identical in a vertical mirror reflection.
Q.54Easy
A regular pentagon is reflected in a horizontal mirror. How many sides will the water image have?
Answer: C
Mirror reflection preserves the number of sides and shape properties. A pentagon remains a pentagon with 5 sides.
Q.55Easy
In a mirror image problem, if the original figure has area 50 cm², the mirror image will have area:
Answer: B
Mirror and water reflections preserve area. The image area equals the original area.
Q.56Easy
Which of the following words appears exactly the same in both mirror and water image?
Answer: C
CIVIC is palindromic and symmetric both horizontally and vertically, so it appears identical in mirror image and water image.
Q.57Easy
If the mirror image of a number reads as '2002', what was the original number?
Answer: A
2002 is a palindromic number that reads the same when mirrored. Each digit (2,0,0,2) appears identical in vertical mirror reflection.
Q.58Easy
A right-angled triangle with legs of length 3 and 4 units is reflected in a horizontal mirror line. What happens to its area?
Answer: B
Mirror reflection is an isometric transformation that preserves distances and areas. The reflected triangle has the same dimensions and area = 6 square units.
Q.59Easy
When the numeral '8' is reflected in a vertical mirror, what appears?
Answer: A
The numeral '8' has vertical symmetry and appears identical when reflected in a vertical mirror line.
Q.60Easy
Which English capital letter looks the same when reflected vertically AND horizontally?
Answer: C
Letter 'H' has both vertical and horizontal symmetry, so it appears identical in both mirror and water image transformations.
