They are measures of angular displacement. In two dimensional space they may be measured in degrees (by beginners) or in radians. There are 2*pi radians in a revolution.
In 3-d space angles are measured in steradians. A sphere measures 4*pi steradians
They are congruent.
4 corners 4 angles Angles add up to 90' All angles are right angles Has 4 lines of symmetry
they have edges and corners and angles and a face :)
180 ANGLES
They're all unequal.

A square has 4 congruent sides and 4 congruent angles
The angles of a triangle and the properties of a chord that intersects it at 7 points are related through the concept of angle bisectors. The angles formed by the chord and the triangle are equal to half the measure of the angles of the triangle that they intersect. This relationship is based on the properties of angles formed by intersecting lines and can be used to find missing angle measures in a triangle.
if you want this answered then what grade are you in?
They're all unequal.
The essential properties are that a rectangle is a quadrilateral whose sides met at right angles. There are many other properties but all of them follow from this.
