1. Angles Project pd.5 By:Chrishard,Odrae,Justin

2. Right Angle-exactly 90 degrees. Example: X+62=90 -62 -62 X=28 Definitions

3. Acute Angle-less than 90 degrees Definitions

4. Obtuse-greater than 90 degrees and less than 180 degrees. Definitions

5. Straight-exactly 180 degrees. Example: Y+77=180 -77 -77 Y= Definitions

6. Complementary-the sum of the measures of two angles is 90 degrees. Example: X + 50=90 -50 -50 X = 40 Definitions

7. Supplementary Angle-the sum of the measures of two angles is 180 degrees. Example: X + 75 = 180 - 75 x = 105 Definitions

8. Vertical Angles- when two lines intersect and form two pairs of opposite angles that are congruent. Example: If “D” equals 20 then “B” equals 20. If “A’’ equals 60 then “C” equals 60. Definitions

9. Adjacent Angles-two angles that share a vertex and a common side do not over-lap. Example: The arrow is pointing at the vertex. And this arrow is pointing at 2 square which mean they are both 90 degrees. Definitions
