The edges of a surface are curves. Is the given statement true or false? Justify your answer

Solution:

We know that

Edges of a surface are known as lines

Therefore, the statement is false.

✦ Try This: It is known that x + y = 18 and that x = z. Show that z + y = 18. Solve using Euclid’s axiom

Given, x + y = 18 --------- (1)

Also, x = z ------------------ (2)

We have to show that z + y = 18

Using Euclid’s second axiom,

If equals are added to the equals, the wholes are equal.

From (2),

x + y = z + y

From (1),

z + y = 18

Therefore, z + y = 18
