Pass Check: 2D Shapes & Properties
Name, sort and find angle facts in polygons using side and angle rules.
Regular polygon
All sides equal length and all interior angles equal.
Interior angle
The angle inside a polygon between two adjacent sides.
Exterior angle
The angle between a side and the extension of the next side; interior + exterior = 180°.
Congruent
Shapes that are exactly the same size and shape (can be rotated or reflected).
