Adjacent Angles
Angles that share a vertex and an entire
side (ray)
ADJACENT ANGLES
– Share a vertex and an entire side

The blue and green angles are adjacent

Linear Pair
Adjacent and the non-shared sides form
a line (when put together, they make a
straight angle)
LINEAR PAIR
– Adjacent & non-shared sides form a line

The blue and green angles form a linear pair
LINEAR PAIR
– Adjacent & non-shared sides form a line

The blue and green angles form a linear pair
LINEAR PAIR
– Adjacent & non-shared sides form a line

The blue and green angles form a linear pair
LINEAR PAIR
– Adjacent & non-shared sides form a line

The blue and green angles form a linear pair
Vertical Angles
Formed when two lines intersect.
These angles are not adjacent - they
are “across from each other.”
VERTICAL ANGLES
– Formed by intersection of 2 lines and are across
from each other (not adjacent)

The blue and green angles are vertical angles
VERTICAL ANGLES
– Formed by intersection of 2 lines and are across
from each other (not adjacent)

The blue and green angles are vertical angles
