WebTo explore angles in parallel lines we will need to use some key angle facts. Angles on a straight line x+y=180^o x + y = 180o (The sum of angles on a straight line equals 180^o 180o) Angles around a point e+f+g+h=360^o e + f + g + h = 360o (The sum of angles around a point equals 360^o 360o) Angles in a triangle A+B+C=180^o A + B + C = 180o WebParallel Lines and Transversals When two lines intersect, four angles are formed that have the same vertex and no common interior points. In this set of four angles, there are two pair of con- gruent vertical angles and four pair of supplementary adjacent angles.

WebAngles that are in the area between the parallel lines like angle H and C above are called interior angles whereas the angles that are on the outside of the two parallel lines like D and G are called exterior angles. Angles that are on the opposite sides of the transversal are called alternate angles e.g. H and B. WebDoes a Triangle have Parallel Lines? No, a triangle does not have any parallel lines. Since a triangle always has 3 intersecting sides; and we know that parallel lines never intersect each other, therefore, a triangle cannot have parallel lines.

WebA rhombus is a four-sided shape where all sides have equal length (marked "s"). Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.
