CBSE Class 3 Mathematics Revision Worksheet Set 05

Question 1. Look at the picture and tell which view of staircase is this?
(a) Top View
(b) Front View
(c) Side view.
Answer: (a) Top View
When we look at a staircase directly from above, we see nested rectangles representing each step, which corresponds to the top view.
In simple words: Looking straight down from the top shows a view from above.
Exam Tip: Always visualize standing right above the object to determine its top view.

Question 2. can be the top of a ________________.
(a) Car
(b) Bed
(c) pencil
Answer: (c) pencil
The circular dot represents the cross-section of a sharp pencil tip viewed from directly above.
In simple words: A sharp pencil viewed from the top looks like a small circle or dot.

Exam Tip: Think about the cross-sectional shape of each object when seen from above.

Question 3. Use the dotted lines to divide the given figures into two similar halves.
Answer: Each given shape can be divided into two identical mirror halves by drawing a straight line of symmetry either horizontally, vertically, or diagonally through its center.
In simple words: Draw a line right down the middle so both sides match perfectly.

Exam Tip: A line of symmetry divides a figure into two identical halves that fit exactly over each other when folded.

Question 4. Guess the English alphabet from their halves.
Answer: (a) A, (b) H, (c) X, (d) D
In simple words: Complete the mirror image of the given half to recognize the capital letter.

Exam Tip: Look at the symmetry line to reconstruct the missing half of symmetrical letters.

Question 5. Which view is this picture showing?
(a) Top View.
(b) Front View.
(c) Side View.
Answer: (b) Front View.
The picture shows the windows, doors, and wheels of a vehicle arranged side by side, which represents how it looks from the front or side profile, corresponding to the front view of a car.
In simple words: The complete outline of windows and wheels facing forward is the front view.

Exam Tip: Identify features like headlights, windshields, and doors to recognize front views.

Question 6. Complete the pattern:-
Answer: Extend the repeating geometric or rotational design by following the exact alternating rotation and shape sequence shown in the worksheet.
In simple words: Follow the design sequence and draw the next repeating shape.

Exam Tip: Check the repeating units carefully before extending any visual pattern.

Question 7. Are identical halves necessarily mirror halves? (Take the hint from the given Figure)
Answer: No. Two halves of a shape can be identical in area or shape when cut or rearranged, but they do not always form a true mirror reflection of each other.
In simple words: Two equal parts are not always mirror images.

Question 8. Tell whether the dotted line in each shape represents line of symmetry.
Answer: (a) Yes, (b) Yes, (c) Yes, (d) No
In simple words: Check if the dotted line divides the shape into two exact matching halves.

Exam Tip: If folding along the dotted line makes both sides overlap completely, it is a line of symmetry.

Question 9. Draw a line of symmetry in each shape.
Answer: Draw a straight vertical line passing exactly through the center of each given symmetrical figure (such as the T-shape, club, house, and cross shape) to split it into two identical mirror halves.
In simple words: Draw a vertical line down the middle of each figure.

Exam Tip: The line of symmetry must pass straight through the middle so that left and right sides are exact reflections.

Question 10. Draw the second half of each symmetrical shape.
Answer: Complete the symmetrical shapes (such as triangles, spades, hearts, and cross patterns) by drawing the exact mirror reflection across the provided symmetry line.
In simple words: Copy the exact shape across the middle line to complete the drawing.

Exam Tip: Measure equal distances from the line of symmetry on both sides while drawing the second half.
