square has 2 equal sides
A straight angle is an angle.
By a straight angle I assume you mean an 180° angle, so two angles that form a 180° angle would be called supplementary angles.
When a ray divides an angle(Which is formed by 2 straight lines) in half that is equally on both the sides, it is termed as Angle Bisector.
The exterior angle sum of ANY plane polygon (ie 2-dimensional figure with straight sides) is 360 degrees.
rhombus

Probably a right angle triangle because it has 2 straight sides that are perpendicular to each other
An angle must have 2 sides or it is no longer an angle.
None. An angle has 2 sides.

A major sector of a curve.
Angles larger than a right angle and smaller than a straight angle (between 90° and 180°) are called obtuse angles ("obtuse" meaning "blunt"). An angle equal to 1. /. 2 turn (180° or π radians) is called a straight angle.
a triangle who has 2 angle and 2 sides that are equal are called.... um... >.>; idk... a isosoleces triangle(not sure about spelling) check it out --> http://www.youtube.com/user/lzzy423
