What else can I help you with?
Does a rectangle have a perpendicular sides?
YES!!! By the fact that is is named a 'Rectangle'. ,the anglesw are all 90 degrees. This means that all the angles are right angles, hence making the sides perpendicular. Quadrilateral means a four sided figure. It is a collective noun for rectangles and non-rectangles. Rectangles are squares, and rectangles. Non-rectangles are , parallelograms, rhombus, trapezium, kite.
What has 2 pairs of parallel sides and no right angle?
Every non-rectangular parallelogram has. (It's not correct to say that a parallelogram has, because rectangles and squares are parallelograms too.)
Are some rectangles also trapezoids?
True. All rectangles are trapezoids. (In England a trapezoid is known as a trapezium.)
Is it true that two rectangles are always congruent?
No, two rectangles are not always congruent. Two rectangles are considered congruent if they have the same dimensions, meaning both their lengths and widths are equal. However, rectangles can have different dimensions and still be rectangles, making them non-congruent.
Is the number line a graph of rational numbers?
The number line includes all rational numbers but also has irrational ones. It is the REAL number line. The square root of non-perfect squares are on it and pi is also on it and they are not rational.

Show you a picture of a non square rectangle?
Click on 'related links' below. The link will take you to some pictures of rectangles some are squares some are not.
What are the examples of quadrilaterals and non-examples of quadrilaterals?
Quadrilaterals are things with four sides, like squares, rectangles, diamonds, trapezoids, rhombuses. Anything that doesn't have four sides (an infinite list) is a non-example of a quadrilateral.
What numbers always have an even number of factors?
All positive integers which are not perfect squares.
What has 2 pairs of parallel sides and no right angle?
Every non-rectangular parallelogram has. (It's not correct to say that a parallelogram has, because rectangles and squares are parallelograms too.)
What solid figure has congruent squares on all six sides?
A cube.
Is all non-perfect squares irrational?
No. 1.5^2 = 2.25 is rational.
Are some rectangles also trapezoids?
True. All rectangles are trapezoids. (In England a trapezoid is known as a trapezium.)
What types of figures tessellations the plane?
All sorts of figures. The only regular polygons that can tessellate by themselves are triangles, squares and hexagons. Irregular polygons such as rectangles, rhombuses, parallelograms and trapeziums will as well. Regular octagons combined with squares will. Other regular polygons can be combined with appropriate star-shapes to tesselate. There are also Penrose tilings which, although they cover the plane, are non-periodic in the sense that the pattern does not repeat itself if you move along. Finally there are many irregular shapes that will tessellate.
Is it true that two rectangles are always congruent?
No, two rectangles are not always congruent. Two rectangles are considered congruent if they have the same dimensions, meaning both their lengths and widths are equal. However, rectangles can have different dimensions and still be rectangles, making them non-congruent.
How can you place 15 coins inside six rectangles such that there are odd numbers of coins inside each rectangle?
Not if the rectangles are non-overlapping.
What are characteristics of non-polygons?
A polygon is usually defined as a plane figure bounded by straight line segments. Any figure which does not correspond to this definition would be a non-polygon. For example, triangles, rectangles, squares, and even star shapes are called polygons. A circle, semicircle or oval is not a polygon. The have curved boundaries.
