adrilaterals/
Identify properties and parts of
quadrilaterals
• What were the properties, volunteers to
present poster/organizer
Summary 2-27-13
• How do you classify quadrilaterals?
• List as many as you can in your notebook,
date, label the question, and I will check
sometime in March when I collect your
notebooks
Do now 3-1-13
• How do you classify quadrilaterals and
triangles
• List all the ways you can remember
Test review
• The measure of a (n) ___________ of a triangle is equal
to the sum of the measures of its two remote (far side)
interior angles.
• The measures of the three angles of a triangle are given.
Find the value of x and tell me the angle degrees.
(complete both 2a and 2b)
– X, 2x, 3x
– X + 10, x – 20, x + 25
• Explain how you find the missing angle measure in a
triangle? Be specific
Test review
• What is the theorem to find the interior angles of a
polygon? Describe how it is used with your favorite
type of polygon.
• What theorem will allow you to prove that the last
pair of angles is congruent?
• How can you find distances on a coordinate plane
without measuring? Describe & provide an example
Congruent triangles
•
•
•
•
•
•
Proving 2 triangles are congruent:
SAS – 2 same ratio, one congruent angle
SSS – deals with proportions/ratios
AAS – same 2 angles and one same ratio side
AA – 2 angles the same (congruent)
HL (hypotenuse leg theorem)
Classify / properties of quadrilaterals
• In your organizer, you must come up with a
creative way to include properties as well
(properties mean how many parallel sides,
congruent angles, etc)
• Use

Vocabulary to include for
quadrilaterals
• Use this vocab in graphic organizer (foldable,
venn diagram, mapping, table grid, concept map,
chart, poster, etc)

Dilation with triangles scale model
• Come up with a model of something you enjoy
• Must use actual measurements and then come
up with scale factor
• Use quadrilaterals in design and/or congruent
triangles
• Will you have any transformations in your
picture, if so which ones and label
• Color, label, key for scale factor, and be creative
Summary 3-1
• How do shapes, transformation, and
properties of shapes assist in business aspects
and everyday life?
