1. Warm Up
What do you recall about the following terms?
Congruent
Acute, Obtuse, Right Angles
Complementary Angles
Supplementary Angles
Vertical Angles
Parallel Lines
Perpendicular Lines
Transversal Line

2. Warm Up What do you recall about the following terms?
Congruent: Two or more angles or sides with equal measures
Acute Angle: An angle that measures less than 90°
Obtuse Angle: An angle that measures more than 90°
Right Angle: An angle that is exactly 90°
Complementary Angles: Angles whose measures have a sum of 90°
Supplementary Angles: Angles whose measures have a sum of 180°
Vertical Angles: Diagonal angles having equal measures formed by two intersecting lines
Parallel Lines: Two or more lines on the same plane that are equidistant thus never intersect
Perpendicular Lines: Lines that intersect at a right angle
Transversal Line: Lines that intersect two or more parallel lines

7. Alternate Angles- Have the same measurement
Alternate Angles- Have the same measurement

9. Vocab
Adjacent Angles- angles that have a common side and a common vertex (corner point)
Corresponding Angles- two parallel lines cut by a transversal then the corresponding angles are congruent

10. Same side angles- when two parallel lines are cut by a transversal the angles are supplementary and so they add up to 180°
