Angles EOG
Question | Answer |
---|---|
angles equal 90 degrees | complementary angle/right angle |
opposite angles equal each other | vertical angle |
angles equal 180 degrees | supplementary angle/straight angle |
∠ | angle symbol |
angles share a common vertex and side | adjacent angle |
If ∠ H and ∠ J are vertical angles, and ∠ H= 57°, then what is the measure of ∠ J? | 57° |
If ∠ E and ∠ F are complementary angles, and ∠ E= 15x° and ∠ F=60° then what is the value of x? | 15x + 60 =90 x=2 |
If ∠ K and ∠ N are supplementary angles, and ∠ K= 5x° and ∠ N=140° then what is the value of x? | 5x + 140= 180 x= 8 |
