Question

1. which of the following objects are symmetrical?

(a) image of a chess piece (b) image of a house (c) image of a tigers face
(d) image of a table (e) image of a knife (f) image of a candle

Explanation:

• (a) Chess piece: It has a vertical line of symmetry. If we imagine a line down the center, both sides are mirror - images.
• (b) House: It has a vertical line of symmetry. The left and right sides (excluding minor details like door placement in some non - strict views) can be considered symmetrical.
• (c) Tiger's face: A tiger's face (in a typical representation) has a vertical line of symmetry. The two eyes, ears, and sides of the nose are symmetrically placed.
• (d) Table: A simple table (assuming a regular shape) has a vertical line of symmetry. The two sides of the tabletop and legs (if symmetrically placed) make it symmetrical.
• (e) Knife: A knife (assuming a simple blade - handle design without asymmetrical decorations) has a vertical line of symmetry. The blade and handle can be divided into two mirror - image halves.
• (f) Candle: A candle (in a basic shape) has a vertical line of symmetry. The cylindrical body and the flame (assuming a symmetric flame shape) are symmetric about the central vertical axis.

Answer:

(a), (b), (c), (d), (e), (f)
