Angles-Polygons-Triangles-Quadrilaterals

Angles-Polygons-Triangles-Quadrilaterals. Angles If two lines cross we say they INTERSECT. If two lines in the same plane do not intersect, we say they are PARALLEL. If two lines make square corners at the point of intersection we say the lines are PERPENDICULAR.
