Polygons & Congruence

Front

What is a polygon?

Back

Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is 'closed' (all the lines connect up).

Front

What is an irregular polygon?

Back

An irregular polygon is a polygon with different sides and different angles.

What is congruence in geometry?

Back

Congruence means that two shapes are the same size and shape.

Front

How do you identify corresponding angles in congruent polygons?

Back

Corresponding angles are angles in the same position in two different polygons.
