Key words: equilateral triangle, isosceles
triangle, scalene triangle, acute triangle,
right triangle, obtuse triangle, non-polygon,
regular polygon, irregular polygon, convex

formula
 I can construct and compare triangles including scalene, isosceles,
equilateral, right, obtuse and acute
 I can sort given triangles and polygons and explain my sorting rule

Explain how you remember how many equal sides each of these
triangles have:
o Equilateral triangle
o Isosceles triangle
o Scalene triangle

How many different ways can you describe a triangle?

Name six types of triangles you know. Which of them do you find
easier to draw? Explain why.
 I can describe and compare the sides and angles of regular and
irregular polygons

List the attributes of a regular polygon. Which strategy do you
prefer to use to check whether a polygon is regular or irregular.

What does it mean when we say two regular polygons are
congruent?
 I can develop a formula to find perimeter, area, and volume of a
polygon

How are the side lengths of a polygon and its perimeter related?
Use examples to explain.

When might you use the formula for the area of a rectangle outside
the classroom?

Explain why the volume of a rectangular prism is the product of its
length, width, and height. Include a diagram in your explanation.
