Two angles that add up to 90 degrees
What are Complimentary Angles?
If two angles are on the opposite sides of the transversal and inside the parallel lines.
What is Alternate interior angles?
Having the same size and shape
What is congruent?
If two angles are vertical. Angle 1 is 64 Angle 2 is 8x Solve for x
x = 8
Two angles that add up to 180 degrees
What are Supplementary Angles?
Opposite sides of the transversal and outside the parallel lines.
What is alternate exterior angles.
A line that intersects two parallel lines.
What is Transversal?
If you have a corresponding pair of angles. 1 is 132 and angle 2 is 3x + 9. Solve for x
x=41
Angles that are across from one another and are congruent.
What are Vertical Angles?
Angles that add up to 90 degrees.
What are Complementary angles?
Have the opposite inverse slope
What is perpendicular?
If two angles are alternate Interior angles and angle 1 is 92 and angle 2 is 8x - 4. Solve for x
x = 12
Lines that never intersect (cross)
What are Parallel Lines?
What are the angles that match each other with a transversal angle?
What is corresponding angles.
Angles that occupy the same position and are congruent.
What are Corresponding Angles?
If two angles form Supplementary angles and angle 1 is 100 and angle 2 is X + 10. Solve for x.
x = 70
Angles that are on the inside of the parallel lines and are across from each other and congruent.
What are Alternate Interior Angles?
Angles that are opposite of each other in the form of an "X"
What are vertical angles?
Angles on the outside of the parallel lines and are across from each other and congruent.
What is Alternate exterior angles?
You a have Vertical angles. Angle 1 is 2x + 9
Angle 2 is 4x - 41. Solve for x
x = 25
