Alternate Exterior
If an angle measures 34 degrees, what type of angle is it?
Acute
Two coplanar angles that share a common side and vertex, but do NOT overlap
Adjacent Angles
Write the equation to solve for x but dont solve!
28o + xo + 73o = 180o
Use the image on the board: Name the angle relationship between angles 9 and 13
Corresponding
An angle that measures 90 degrees
Right Angle
Vertical angles are __________
Congruent (the same)
What is the measurement of angle x?
28o + xo + 73o = 180o
xo = 180o - 28o -73o
xo = 79o
