Examples of regular shapes?
Regular shapes are shapes where all the sides and angles are equal. One example of a regular shape is a square because all the sides are the same and all the angles are 90 degrees.
How are regular and irregular shapes the same?
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
What has no congruent sides and no congruent angles?
Irregular polygons, curves, open shapes all lack congruence of angles and sides.
What are called shapes having many sides and angles?
Polygons
Do any 2D shapes have no straight sides but have right angles?
No
How many angles does a hexagon have?
A 6 sided hexagon has 6 angles that add up to 720 degrees
How many angles in a 12 sided polygon?
All polygons have the same number of sides as angles. So if there are 12 sides, thereare 12 angles.
