Polygon

Polygons

Polygons

• Poly (means many) & gon (side)

• the sides are straight lines

• none of the line segments can cross one another

• the shapes are closed

Multiple Choice

What is a polygon?

• A closed figure made up of curved edges

• An open figure made up of straight line segments

• A closed figure made up of crossed line segments.

Not a polygon

​

• ​Sides that intersect

Multiple Choice

Which one is a polygon?

Multiple Choice

Which one is NOT a polygon?

Multiple Choice

Which one is a polygon?

​Some text here about the topic of discussion.

• Regular: all the angles are equal and all the sides are equal.

​

Multiple Choice

A polygon is regular if:

• Only all angles are equal.

• All angles are equal and all sides are equal

• Only all sides are equal

• All sides have different measurements

Polygons are named according to the number of sides and angles they have.

​

For example: a triangle has three sides, a pentagon has five sides, a dodecagon has twelve sides.

​

Multiple Choice

Whatever their shape, all polygons are made up of the same parts:

sides, vertices (connecting points), and angles (inside and outside the shape).

Multiple Choice

What is a vertex?

• The point where two waves meet

• The point where two sides meet

Triangles

Triangles are the shapes with 3 sides and 3 corners. int the given figure, we can sea a triangle ABC.
According to its sides, Triangles are of three types:                                 
 1.Equilateral
2. Isosceles
