Parallel lines and triangles
WebParallel lines in triangles and trapezoids. The intercept theorem can be used to prove that a certain construction yields parallel line (segment)s. If the midpoints of two triangle sides are connected then the resulting line segment is parallel to the third triangle side (Midpoint theorem of triangles).

When two parallel lines are intersected by a third line, the sum of any large angle and any small angle is 1800, because they are supplementary angles. Therefore, a + x = 180 and b + y = 180. Triangles 11. Every triangle has three sides. If you add the lengths of any two of those sides, the sum will always be larger than the length of the ...
