THE COMMON ENDPOINT OF AN ANGLE. WHERE THE SIDES MEET

LINE THE STARTS AT ONE POINT. LINE THAT GOES ON FOREVER.

ANY LINE SEGMENT FROM THE CENTER. IS HALF A CIRCLE

OF CONTINUOUS POINTS EQUALY DISTANT FROM THE POINT. ITS A CIRCLE THAT HAS A POINT IN THE MIDDLE

A PLANE HAS TWO DIMENSIONS. ANYTHING THAT HAS A FLAT SURFACE

EXACTLY 90. THAT ADD'S UP TO 90

LINES RUNNING ACROSS. THAT IS CROSSING PATHS WITH EACH OTHER

ALL SIDES ARE EQUAL. THE SIDES ARE THE SAME
