  1. 1-4 Angles

  2. Angle: Figure made when 2 rays have the same endpoint • EF and ED are the sides • E is the vertex • Called: • RULE: Vertex MUST be in the Center when naming an angle D 1 E F

  3. TOO • Name as many different angles as you can P Q S R

  4. Types of Angles • Acute Angle: Measures between 0º and 90º a “cute”: little • Right Angle: Measures 90º • Look for the box in corner • Obtuse Angle: Measures between 90º and 180º • Straight Angle: Measures 180º

  5. If B is in the interior of angle AOC, then AND A B O C

  6. Bisector of an Angle • A ray that cuts an angle in half • Similar to a midpoint A B O C

  7. LA bisects angle GLH, therefore . . . • Solve for x if: H A G L
