Parallel lines cut by a transversal a line that crosses parallel lines is a transversal. In each diagram, parallel lines are cut by a transversal and the measure of one angle is given. If you dont see any interesting for you, use our search form on bottom v. Vertical angles are congruent which means they have the same measure. Write the measures of the remaining angles on the diagram. Parallel lines and transversals transversal a transversal is a line which intersects two or more lines in a plane.
Follow the steps to illustrate the postulate and use it to find angle measures. It starts with an investigation activity in which students discover properties of corresponding angles. Label all 8 angles starting with 1, 2, 3 and so on. If two lines are cut by a transversal such that the alternate interior angles are. Chapter 3 parallel and perpendicular lines study guide. Do not editchanges must be made through file info name.
If the transversal is not perpendicular to the parallel lines, then four angles are acute and four are obtuse. Parallel lines and transversals in the picture below, lines x and y ore lines, and line t is a or a line that intersects them, use a protractor to measure each of the 8 angles that were formed. If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary. Sameside interior angles postulate if two parallel lines are cut by a transversal, then the pairs of sameside interior angles are supplementary. Angles formed by parallel lines and transversals duration. Identify each pair of angles as corresponding, alternate interior, alternate exterior, or consecutive. Supplementary angles are two angles that add up to 180 they make a straight line. Using the figure below, state the transversal that forms each pair of angles.
