  1. Lesson 1.4 Measuring and Classifying Angles

  2. Objective • Name, measure, and classify angles

  3. Standard 1.0 • Students will demonstrate understanding by identifying and giving examples of undefined terms, axioms, theorems, and inductive and deductive reasoning

  4. Angle • Consists of two different rays with the same endpoint.

  5. Vertex • Endpoints of rays in a angle

  6. Angle A or The angle with sides AB and AC can also be named or

  7. Example • Name 3 angles

  8. Degrees are the unit of measure for an angle • Angles are measured in degrees because they are a portion of a circle.

  9. Classify Angles Use a protractor to measure angles

  10. Angle Addition Postulate • If P is in the interior of , then the measure of is equal to the sum of the measures of and

  13. Congruent Angles • Angles with the same measure A B

  14. Angle Bisector • A ray that divides an angle into two angles that are congruent
