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

State whether the following statement is True or False. Justify your answer.
If the area of a triangle equals the area of a rectangle and the area of the rectangle equals that of a square,then the area of the triangle also equals the area of the square.

In the figure,if $\angle 1 = \angle 3$,$\angle 2 = \angle 4$ and $\angle 3 = \angle 4$,write the relation between $\angle 1$ and $\angle 2$,using an Euclid's axiom.

The number of dimensions a solid has is:

Solve the following question using appropriate Euclid's axiom:
It is known that $x+y=10$ and that $x=z$. Show that $z+y=10$.

Euclid's fifth postulate is:
