1) These pairs of angles are vertically opposite angles.
These pairs of angles are not vertically opposite angles.
a) Which of these angles are vertically opposite angles?
b) Give a definition of vertically opposite angles.
(Hints: What can you say about their vertices? What can you say about their sides?)
2) These pairs of angles are adjacent angles.
These pairs of angles are not adjacent angles.
a) Which of these angles are adjacent angles?
b) Give a definition of adjacent angles.
(Hints: What can you say about their vertices? Where is their common side?)
3) These pairs of angles are supplementary angles.
These pairs of angles are not supplementary angles.
a) Which of these angles are supplementary angles?
b) Give a definition of supplementary angles. (Hint: Add their measures).
