Hey Everybody! It’s your old pal Big Bird!. We are here to learn quadrilaterals.

6.14 Polygons The student will identify, classify, and describe the characteristics of plane figures, describing their similarities, differences, and defining.

Exploring Polygons. What are polygons? A polygon is a closed figure made by joining line segments, where each line segment intersects exactly two others.

Warm-up 1.. NOTES - Polygons Polygons are classified by the number of sides it has: Pentagon – 5 Hexagon – 6 Heptagon – 7 Octagon – 8 Nonagon – 9 Decagon.

Polygons Lesson What is a polygon? A polygon is a simple, closed, two-dimensional figure formed by three or more line segments (sides). Closed?

Our learning objectives today: To be able to recognise and name 2D shapes. To know about quadrilaterals.

What shapes are these? Identify the Faces, Edges, Vertices.

Names of Angles

Describe the figure using all applicable terms. It is a rectangle since it has four right angles. It is a parallelogram since it has two pairs of parallel sides. It is also a trapezoid since it has at least one pair of parallel sides.
