POINTS, LINES AND PLANES Section 1-1

What is Geometry? Geometry is the study of shapes They studied Geometry in Ancient Mesopotamia & Ancient Egypt Geometry is important in the art and construction fields

POINT A POINT is an exact location on a graph, shape or in space. The ball is a POINT on the line.

LINE A LINE goes in opposite directions and never, ever ends. Take a pearl necklace and stretch it out. The pearls are like points on a line.

PLANE A PLANE is a flat surface that goes on forever in all directions. Imagine sitting on an island in the middle of the ocean. No matter which way you look…all you see is water…forever.

TO NAME A POINT- WE USE A CAPTIAL LETTER .X

TO NAME A LINE- USE ANY 2 POINTS ON THE LINE LINE RT or LINE ST or LINE RS R T S RT RS

POINTS ON THE SAME LINE ARE CALLED COLLINEAR POINTS A, B, AND Y ARE COLLINEAR . . Y . B A

TO NAME A PLANE WE USE 3 OR 4 NONCOLLINEAR POINTS PLANE WAG or XAG or WXA . .A X Q .W .G PLANES CAN BE NAMED USING 1 LETTER …. PLANE Q

THE INTERSECTION OF 2 LINES IS A POINT S IS THE INTERSECTION OF THE 2 LINES

LINE AB IS CONTAINED IN PLANE Q

LINE XY INTERSECTS PLANE Q AT POINT X . X

THE ARROW INTERSECTS THE TARGET AT 1 POINT

Lines YB and XZ do not intersect . Y . B X

THE INTERSECTION OF 2 PLANES IS A LINE D G B C E E G H C F

POINTS AND LINES CONTAINED IN THE SAME PLANE ARE CALLED COPLANAR Y W. S. P X G.
