When we have a pair of lines, they can be 1 parallel 2 perpendicular 3 intersecting angle. An angle whose measure is bigger than 90 degrees but less than 180. We divide the areas created by the parallel lines into an interior area and the exterior ones.
When two lines are intersected by a transversal, eight angles are formed. Song 10 min next, i taught students a song to help them remember the types of triangles. In a parallelogram, angles next to each other make a c shape interior angles. When a transversal cuts or intersects parallel lines several pairs of congruent and supplementary angles are formed. We also study how the size of the angle is only determined by how much it has opened as compared to the whole. This is a type of polygon that consists of three sides with three apexes.
