Unit 3 - Parallel and Perpendicular Lines

Geometry

Unit 3

Parallel and Perpendicular Lines

18 days

3.1  Define, identify, and label parallel lines and planes, skew lines, and transversals.

3.2  Define, identify, and label alternate interior and exterior angles, consecutive interior and exterior

angles, and corresponding angles and use these to find missingmeasurements given a numeric value or algebraic

expression.

3.3  Prove that two or more lines are parallel using the converse of angle pairs.

3.4 Derive and use the slope formula to find the slope of a line given a graph or set of points.

3.5  Using their slopes, determine if two lines are parallel, perpendicular, or neither.

3.6  Write the equation of a graph in slope-intercept form.

3.7  Covert the equation of a line to slope-intercept form.

3.8  Given the equation of two lines, determine if they are parallel, perpendicular, or neither by converting to

slope-intercept form.

3.9  Using the point-slope form of a line, write its equation given a point and slope, two points, or a point and the

slope of a line parallel or perpendicular.
