A vertex is a corner or a point where lines meet. Those lines are called rays or segments.
Lines that cross each other are called intersecting lines.
Straight lines that never cross are called parallel lines.
They are perpendicular lines
Two (the diagonals, from corner to opposite corner)
On the 32" x 32" square draw two diagonal lines from corner to corner to form a cross. Where the two lines cross marks the centre of the big square.From this centre point, draw a horizontal line to the side perimeter of the big square. Then from the centre point draw a vertical line down to the bottom of the big square.You have now formed a 16" x 16" square inside the big square.
To find the centre of a square or rectangular board, draw a diagonal line from corner to corner. Repeat for the remaining two corners. Both lines will cross over at the centre of the board.
The lines that cross at a 90 degree angle are called Perpindicular lines.
A shape that contains at least two distinct intersecting lines is a figure called a cross. A cross consists of two lines that intersect perpendicularly at their midpoint.
