Which shapes have right angles and parallel lines?
Rectangles and squares
What has 2 right angles and 2 parallel lines?
A square or rectangle are the only regular polygons, but many other shapes have two right angles and two parallel lines.
What 2 shapes have 4 right angles and 2 pairs of parallel sides?
a square and a rectangle
What is another name for a plane figure that has sides and angles and is closed?
Polygon
How many parallel sides are on a nonagon?
There are no parallel sides on a nonagon (nine-sided figure)... Regular shapes with an odd-number of sides have no parallel sides.
What shapes have opposite angles congruent?
Any polygon with 2n sides (n integer) where opposite sides are parallel, will have its opposite angles congruent.
What is the importance of angles to shapes and or angles?
Some shapes have angles and so they are important in defining the shapes. And angles are absolutely critical for angles. They are the very essence of their existence: if it were not for angles then there would be no angles.
How do you decide a figure is congruent?
If all the sides and all the angles are the same and in the same order, the shapes are congruent.
How is a square similar to a rectangle?
Both shapes have 4 sides, 4 right angles and 2 parallel pairs of lines.
What is a rectilinear figure?
A rectilinear figure is a polygon such that all its sides meet at right angles. The only convex shapes are a rectangle (or square), but it can also be a concave shape with some interior angles of 270 degrees.
