CBSE Class 4 Maths Shapes And Patterns Worksheet Set 02

TOPIC- SHAPES, SPACE AND PATTERN

Question 1. Mirror mirror Which two images mirror each other circle them
a.
Answer: Examining the four house outlines from left to right (let us number them 1, 2, 3, 4):
- House 1 and House 2 are mirror images of each other because the triangular roof overhang and base are reflected horizontally across a central vertical line.
- Therefore, circle House 1 and House 2.
In simple words: Two figures are mirror images if one looks like the exact reflection of the other in a looking glass.

Exam Tip: Look closely at the orientation of asymmetrical parts, such as roof overhangs or flags, to determine correct mirror pairs.

Question 1(b). Which two images mirror each other circle them (b)
Answer: Examining the four sailboat outlines from left to right (1, 2, 3, 4):
- Sailboat 1 and Sailboat 2 are exact mirror reflections of each other across a vertical dividing line.
- Therefore, circle Sailboat 1 and Sailboat 2.
In simple words: Match the boat pointing in the opposite horizontal direction as its reflection partner.

Exam Tip: Pay attention to which direction the mast or flag leans to identify mirror pairs quickly.

Question 2. Draw a line of symmetry on each shape
a. Butterfly
Answer: A vertical line of symmetry passes straight down through the center of the butterfly's head, body, and tail, dividing the left and right wings into two identical halves.
In simple words: A line of symmetry divides a shape into two matching, equal halves.

Exam Tip: Ensure the line splits the central body exactly in half so both wings mirror each other perfectly.

Question 2(b). Draw a line of symmetry on each shape
b. Car outline
Answer: A standard side-profile outline of a car is generally asymmetric because of features like the front and rear windshield slopes or doors, but if considering a top or front-facing car view, a vertical line divides it. For a standard symmetric top view, a vertical line runs from front to back down the exact middle.
In simple words: Look for the central axis where the left and right sides match.

Question 2(c). Draw a line of symmetry on each shape
c. Snowflake / Complex decorative shape
Answer: This decorative star-like shape possesses multiple lines of symmetry passing through opposite vertices and midpoints. At least two primary perpendicular lines of symmetry (one vertical and one horizontal) divide the shape into matching symmetrical quadrants.
In simple words: Complex symmetric patterns have multiple lines passing right through their center.

Exam Tip: For regular polygonal and star patterns, count the matching points to determine all possible lines of symmetry.

Question 3. Draw the mirror image of the following and complete the shape.
a. Curved abstract shape next to a vertical mirror line
Answer: To complete the shape, reflect every curved loop and line segment across the vertical mirror line to the right side at an equal perpendicular distance, forming a symmetrical butterfly-like curved pattern.
In simple words: Copy the exact shape onto the other side of the mirror line as if reflected in a mirror.

Exam Tip: Measure the perpendicular distance of key points from the mirror line to plot the reflected points accurately.

Question 3(b). Draw the mirror image of the following and complete the shape.
b. Letter A split by a vertical mirror line
Answer: Reflect the left half of the letter across the vertical mirror line to complete the full capital letter A symmetrically.
In simple words: Complete the other half of the letter A by drawing its mirror reflection.

Exam Tip: Standard capital letters like A, M, T, V, W, Y possess vertical lines of symmetry.

Question 3(c). Draw the mirror image of the following and complete the shape.
c. Half face with a zig-zag border
Answer: Reflect the visible eye, curved profile, and zig-zag border across the vertical mirror line to complete the full symmetrical face design.
In simple words: Mirror the exact features and zig-zag pattern onto the empty side.

Exam Tip: Maintain exact proportions and distances from the mirror line for a clean symmetrical completion.
