Exploring Regular and Irregular Polygons

The video tutorial explains the concepts of regular and irregular polygons. Regular polygons have equal sides and angles, with examples including squares, equilateral triangles, and hexagons. Irregular polygons have sides or angles that are not equal, with examples such as rectangles, isosceles triangles, and parallelograms. The video concludes with a summary of these concepts.

How many degrees are each angle in an equilateral triangle?

• 180 degrees

• 45 degrees

• 60 degrees

• 90 degrees
