Review of Polygons
What are the 3 aspects that make a shape a polygon?
1. Closed Shape
2. 3 or more sides
3. Only line segments
How many types of triangles are there?
6
What instrument is used to measure angles?
Protractor
What is congruence?
means corresponding sides are equal and/or corresponding angles are equal.
Name two of the shapes that are considered a quadrilateral.
Parallelogram, Rectangle, Square, Rhombus, Trapazoid
If a triangle has all the same size line segments and angles, what kind of triangle is it?
Equilateral
What is the point where 2 line segments meet to form an angle?
Vertex
Hypotnous Leg
the hypotenuse and a leg of one triangle are congruent to the hypotenuse and a leg of another triangle.
Describe the difference between a hexagon and a heptagon.
A hexagon has 6 sides, angles, and vertices.
A heptagon has 7 sides, angles, and vertices.
By their size or angles
Describe the difference between a supplementary angle and a complementary angle.
Supplementary angles are 2 angles next to each other that add up to 180 degrees and form a straight line.
Complementary angles are 2 angles next to each other that add up to 90 degrees and form a right angle.
SSA and AAA
Where do the prefixes for the polygons come from? What do the prefixes tell us?
Latin
The number of sides in the shape.
Can a triangle be more than 1 type of triangle? Explain.
Yes, Answers will vary
How are vertical angles and adjacent angles similar?
They are both a pair of angles
What is the difference between a postulate and a theorem?
A postulate is a statement that is believed to be true with little or no proof.
The theorem is a statement that true based upon mathematical reasoning and procedures.
