How many pairs of parallel sides does a decagon have?
It has 3 pairs of parallel sides By the way parallel sides are sides that never intersect (meet or touch together)
What is the truth value of a statement a square has 4 congruent sides and a rectangle has 4 parallel sides?
It is false. The first part about the square is true, but the second part is false. A rectangle has two pairs of parallel sides. The "and' means that both parts must be true for the statement to be true. A convex polygon can have many pairs of parallel sides, but you can never have 3 or more sides all parallel to each other.
How many pairs of parallel sides does a quadrilateral have?
A quadrilateral has 4 sides, 2 in which never intersect. Therefore, the lines that don't intersect are called parallel. There are 4 parallel sides but has 2 pairs of parallel sides.
How many pairs of parallel sides does a circle have?
A circle does not have any pairs of parallel sides. In geometry, parallel sides are defined as sides that are always the same distance apart and will never intersect. Since a circle is a curved shape with no straight sides, it does not have any pairs of parallel sides.
How many parallel sides of a square?
Depends, if you mean 2-D it would be 2. If you mean 3-D (a cube) I belive it would be 3. ADDED: To expand that a little, a Square has 2 Pairs of parallel sides. A Cube has 6 faces, each a square.
