Section 3.1 (Special angles formed by parallel lines cut by a transversal.notebook 1 September 19, 2011 Objective: I can identify parallel lines, skew lines, transversals, alternate interior angles, alternate exterior angles, corresponding angles and consecutive interior angles. answer choices 30 seconds . SURVEY . You can sum up the above definitions and theorems with the following simple, concise idea. Two lines cut by a transversal line are parallel when the sum of the consecutive exterior angles is $\boldsymbol{180^{\circ}}$. If two non-parallel lines are cut by a transversal: 1. A) same side interior angles. angles between 2 lines and on opposite sides of a transversal. angles that are both on the same side of the transversal and on the exterior of the pair of parallel lines. Whose one of the arms includes the transversal, Lie outside the region between the two straight lines. have different vertices. Consecutive Interior Angles Theorem Show Step-by-step Solutions Exterior angles. (X—vertical angles, T—linear pair, F—corresponding angles, Z or N—alternate interior angles, C or U— same side (consecutive) interior angles, two Vs or Ls on opposite sides of the transversal—alternate exterior angles, Vs or Ls on the same side of the transversal same side (consecutive)—exterior angles. An exterior angle among line constructions (not polygons) is one that lies outside the parallel lines. Same-side exterior angles: Angles 1 and 7 (and 2 and 8) are called same-side exterior angles — they’re on the same side of the transversal, and they’re outside the parallel lines. Use same side interior angles to determine supplementary angles and the presence of parallel lines. ___ are exterior angles that are on the same side of the transversal. Same Side Interior and Same Side Exterior Angles Geometry Reasoning, Diagonals, ... kite area diagonals consecutive sides vertex angle non vertex angle bisect perpendicular rhombus. 500. Consecutive exterior angles posted Dec 1, 2012, 4:24 PM by Ray Kim If parallel lines are cut by a transversal line, then consecutive exterior angles are supplementary. Convex Polygon A polygon whose interior angles are all less than 180 degrees. Collinear. With respect to angle 7 for example we say that angle 1 is the opposite interior angle on the same side. 4. 6. Are vertical angles congruent? Consecutive exterior angles. What is the measure of m<10? More commonly called consecutive interior angles. Alternate Exterior Angles. Consecutive Angles Angles in a polygon that share a segment as one of the sides that could be extended into a ray. transversal line definition. Each pair of these angles are outside the parallel lines, and on the same side of the transversal. Angle C and P are... answer choices ... Q. Angles on the same side of a transversal, in corresponding positions, and are congruent are called _____. Exterior Angles are created where a transversal crosses two (usually parallel) lines. These angle relationships are consecutive interior angles, otherwise known as same-side interior angles, and consecutive exterior angles, otherwise known as same-side exterior angles. When the exterior angles are on the same side of the transversal, they are consecutive exterior angles, and they are supplementary (adding to 180 °). 500 ___ points lie on the same line. When two lines are crossed by another line (which is called the Transversal), the pairs of angles: • on one side of the transversal • but inside the two lines are called Consecutive Interior Angles. Consecutive interior angles are the two pairs of angles that: have distinct vertex points, lie on the same side of the transversal and; are both interior. Calculation: They lie on the exterior of the parallel lines and the same side of the transversal, so they should be called consecutive exterior angles.
