Presentation Transcript

G.CO.1 Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc.

G.CO.12 Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.).

Mathematical Practices

5 Use appropriate tools strategically.

6 Attend to precision.

CCSS

• Measure and classify angles.

• Identify and use congruent angles and the bisector of an angle.

Then/Now

• Ray

• a part of a line that has one endpoint and then extends infinitely in the other direction

**Name always begins with the endpoint

Vocabulary

• Opposite rays

• choose a point on a line and either side are called opposite rays

Vocabulary

• Angle

• formed by two noncollinear rays (sides) that have a common endpoint (vertex)

Vocabulary

• Interior

• “inside the angle”

• Exterior

• “outside the angle”

Vocabulary
