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
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

Alternate Angles- Have the same measurement Alternate Angles- Have the same measurement
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
Same side angles- when two parallel lines are cut by a transversal the angles are supplementary and so they add up to 180°
