Complete Euclid's Five Postulates:

• segment

• indefinitely

• center

• congruent

• parallel

A _________________________ is a specific location in space. It is the only zero-dimensional object.

• Point

• Line

• Circle

• Square

Say 'TRUE' or 'FALSE'
If two circles are equal, then their radii are equal

• TRUE

• FALSE

The number of dimensions a surface has ____

• 1

• 2

• 3

• 0

Say 'TRUE' or 'FALSE'
Two distinct intersecting lines cannot be parallel to the same line

• TRUE

• FALSE

'Lines are parallel if they do not intersect' is stated in the form of_____

• An axiom

• A definition 

• A postulate

• A proof

In geometry, we take point, line and plane as undefined term.

• True

• False

What was Euclid's second postulate ?

• A circle can be drawn with any center and any radius.

• If a straight line falling on two straight lines makes the interior angles on the same side of it taken together less than two right angles, then the two straight lines, if produced indefinitely, meet on that side on which the sum of angles is less than two right angles.

• A straight line may be drawn from any one point to any other point.

• A terminated line can be produced indefinitely

A ________ is a surface which lies evenly with the straight lines on itself.

The number of dimensions, a surface has :

• 1

• 2

• 3
