These angles are (Image 2 on board)
Are they the same size or different?
Alternate angles
In a triangle: Angle A is 34, Angle B is 110, and Angle C is 2X. What is the value of X?
18
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
These angles are (Image 3 on board)
What do these two angles add up to?
co-interior
