The number of dimensions a point has is:

State whether the following statement is true or false:
Only one line can pass through a single point.

The $\ldots \ldots \ldots$ was an important manual for geometric structures in ancient India.

If a straight line falling on two straight lines makes the interior angles on the same side of it,whose sum is $120^{\circ}$,then the two straight lines,if produced indefinitely,meet on the side on which the sum of angles is

Euclid stated that all right angles are equal to each other in the form of

If a point $C$ lies between two points $A$ and $B$ such that $AC = BC$,then prove that $AC = \frac{1}{2} AB$. Explain by drawing the figure.
