Question

Match the following

• A. (1)–(iii), (viii); (2)–(i), (iv); (3)–(ii), (vi); (4)-(ii),(v); (5)–(iii), (iv); (6)–(i) (vii); (7)–(ii), (iv)
• B. (1)–(ii), (vii); (2)–(i), (vii); (3)–(iii), (iv); (4)-(i),(v); (5)–(ii), (vi); (6)–(i) (vi); (7)–(i), (iv)
• C. (1)–(ii), (vii); (2)–(i), (iv); (3)–(ii), (vi); (4)-(ii),(v); (5)–(ii), (iv); (6)–(i) (viii); (7)–(iii), (iv)
• D. (1)–(ii), (vii); (2)–(i), (iv); (3)–(ii), (vi); (4)-(ii),(iv); (5)–(i), (viii); (6)–(iii) (iv); (7)–(iii), (vii)

Answer 1

The correct option is A

(1)–(iii), (viii); (2)–(i), (iv); (3)–(ii), (vi); (4)-(ii),(v); (5)–(iii), (iv); (6)–(i) (vii); (7)–(ii), (iv)

First, we have to look what is a, b, c, $\alpha ,\beta ,and\gamma$

Here, a, b and c are three different directional edges, for example, length, breath and width of a 3-dimensional structure.

$\alpha \to$ Angle between a and b

$\beta \to$ Angle between b and c

$\gamma \to$ Angle between a and c

Now, Take a look at this table.

Therefore, (A) is the correct option.
