Find the angle measures for angles 1,2,3, & 4.

5-2 Parallel and Perpendicular Lines

…with the help of Kinto Sol

5-2 Parallel and Perpendicular Lines Measure each angle and write down any observations you make about how the angles are related.

5-2 Parallel and Perpendicular Lines What did you notice???

Parallel Lines: two lines that never meet

Perpendicular Lines: intersect at 90 degree angles

Transversal: a line that intersects two or more other lines

Congruent Angles formed by a Transversal

If two parallel lines are intercepted by a transversal: •Acute angles are congruent •Obtuse angles are congruent •Any acute and obtuse angle are supplementary (they add up to 180 degrees)

Alternate Interior Angles

Alternate Exterior Angles

Corresponding Angles
