What is a closed shape whose sides are all straight lines?
any polygon
Are two adjacent angles whose exterior sides are opposite rays always complementary?
No? Wouldn't they then be supplementary? Opposite rays make a straight angle/line, and if the exterior sides made the straight angle, the adjacent angles would be supplementary. ...Right?
How many angles and parallel lines are in a kite?
A kite has no parallel sides but it is a 4 sided quadrilateral whose 4 interior angles add up to 360 degrees
What makes a regular hexagon?
A plane shape whose six boundaries are straight sides of equal length and each of whose interior angles measures 120 degrees.
How do I find if 2 D shapes are similar?
They must have all angles which are the same, all of whose straight lines are in the same ratio and whose curves have radii of curvature in the same ratio.
What is a closed shape whose sides are all straight lines?

What is two angles whose sides are opposite rays?
If I understand the question: Either pair of opposite angles formed by the intersection of 2 lines.
Are two adjacent angles whose exterior sides are opposite rays always complementary?
No? Wouldn't they then be supplementary? Opposite rays make a straight angle/line, and if the exterior sides made the straight angle, the adjacent angles would be supplementary. ...Right?
Is a polygon that has all congruent faces and angles a concave polygon?
No it is not. On a number of counts.A polygon is an enclosed plane area whose boundaries comprise straight lines. It is, therefore, a 2-dimensional object and so does not have faces. If you meant sides instead, the answer is still NO. If all the sides and and angles are congruent then the polygon MUST be convex.
A pair of adjacent angles whose noncommon sides are opposite rays?
A pair of adjacent angles whose non-common sides are opposite rays are called a linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

What are a pair of adjacent angles called whose non-common sides are opposite rays?
A pair of adjacent angles whose non-common sides are opposite rays are called a linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Two angles whose sides are opposite rays are?
Vertical angles
Does a polygon have to have equal sides?
No, it does not. A polygon is an enclosed plane area whose boundaries comprise straight lines. There is no requirement for the sides to be equal. If they are, the polygon is said to be equilateral.
How do I find if 2 D shapes are similar?
They must have all angles which are the same, all of whose straight lines are in the same ratio and whose curves have radii of curvature in the same ratio.
What is the name of a parallelogram whose sides are equal length but whose angles are not necessarily right angles?
It's called a 'Rhombus'.
