Ohio Content Standards:
Ohio Content Standards:
Formally define geometric figures.
Ohio Content Standards:
Recognize and apply angle relationships in situations involving intersecting lines,
perpendicular lines and parallel lines.
Ohio Content Standards:Recognize the angles
formed and the relationship between the angles when two lines
intersect and when parallel lines are cut by a
transversal.
