When a straight line XY cuts two parallel line PQ and RS [as shown in figure], the following are the relationships between various angles that are formed. [M and N are the points of intersection of XY with PQ and RS respectively].

a) alternate angles are equal
i.e, angle PMN = angle MNS
angle QMN = angle MNR
b) corresponding angles are equal
i.e, angle XMQ = angle MNS
angle QMN = angle SNY
angle XMP = angle MNR
angle PMN = angle RNY
c) Sum of interior angles on the same side of cutting line is equal to 180⁰
i.e, angle QMN + angle MNS = 180⁰
angle PMN + angle MNR = 180⁰
d) Sum of exterior angles on the same side of transversal line is equal to 180⁰
i.e, angle XMQ + angle SNY = 180⁰
angle XMP + angle RNY = 180⁰
If three or more parallel lines make equal intercepts on one transversal, they make equal intercepts on any other transversal as well.

An improved carrier case for carrying a pair of roller skates or ice skates or boots or other shoe-like articles comprising a first and second article compartment means for enveloping one each of a pair of said articles, respectively, each of said first and second compartment means being substantially L-shaped to closely approximate and surround the air jordan shoes shape of said enveloped article; each said article restraint means comprising one or more fixture devices in the bottom of said respective compartments, said fixture devices each having a top surface exposed to said article and having one or more indentations therein for snug and aligned receipt of a michael jordan shoes corresponding complementary portion of the article to be restrained within said compartments; and resealable entry means in each of said compartments for alternately exposing and sealing the interior of each of said compartment means to a user whereby insertion, storage and removal of the respective articles into and from said compartments may be effectively accomplished.
