Question

Euclidean geometry is valid only for curved surfaces.

• A. True
• B. False
• C. Sometimes True
• D. Data Insufficient

Answer 1

Answer: (B)

False

Euclid's postulates:

$\Rightarrow$ A straight line can be drawn joining any two points.

$\Rightarrow$ A straight line segment can be extended indefinitely in a straight line.

$\Rightarrow$ A circle can be drawn having the segment as radius and one endpoint as center.

$\Rightarrow$ All right angles are congruent and equal.

$\Rightarrow$ Parallel postulate.

Hence, we can observe that euclidian geometry is valid for 2-dimensional geometrical figures.
