Polygons 3-D Shapes Angles Turns or Symmetry Geometry in the real world

Show the number with your fingers… 1.Visualize an octagonal prism. 2.How many faces does this prism have? 10

Name it! They share this base A.B.B. Pentagonal pyramid Pentagonal prism

Examine this triangular pyramid. How many faces? How many edges? How many vertices? 5 faces 9 edges 6 vertices

What are these quadrilaterals called? Kites

Who am I? Hexagonal pyramid

What type of polygons are displayed below? Not Regular Polygons

The polygon on the right is a convex polygon. What kind of polygon is displayed on the left? A concave polygon

How many vertices do I have? 8

Which quadrilateral has all right angles? rectangles

Which shape would you describe as having corners that are: a)All right angles? b)Less than a right angle? c)More than a right angle

Match the congruent polygons! F D C G A B E

How could you describe the angle formed by the laptop computer? More than a right angle!

Are these polygons congruent?

50 Free Points!!

What polygon am I? trapezoid

This is a top view of an object. What is the object? Coffee cup

What shape do you see? 8 sides = octagon

What Shapes do you see? Hexagons in the bee hive!

What shape do you see? pyramids

A If A is the original rectangle, would we describe the turn as clockwise or counter clockwise? clockwise

How could we describe the turn made by the arms on the clock. a) a quarter clockwise turn b) a half clockwise turn c) a quarter counter clockwise turn a quarter clockwise turn

Appoint two people on your team to stand up and model 4 clockwise turns. What type of turn did your team mates make after the fourth turn?

How many reflective lines of symmetry does this scalene triangle have? No lines of reflective symmetry

Look around your classroom and find an example of a right angle!
