• Tee- intersecting pipes

• &a'i"s- is the length of a line segment from its

center to its perimeter .

• Intersecting %ines- Lines that have one and only

one point in common.

• Circ"m(erence - is the linear distance around

the edge of a closed curve or circular o!ect.

The Steps in Creating Tee Joint Stretch OutPattern

*. +ra$ line A vertically and line ) hori,ontally enough

space efore reaching the margin# using ruler /cm0

1. 2et the compass to 1.3 cm as the radius of thecylinder

/. +ra$ a half-circle using a compass $ith the

intersecting point of line A and )

4. +ivide the half circle into si5 e6ual parts using a /77-

877-977 triangle and numer it from one to seven



3. %ro!ect do$n$ards all the intersecting points of the

half-circle

8. Lay-out the cylinder sho$ing its front vie$ such that

its height is *7 cm

:. %ro!ect the : numered lines of the half-circle in to

the front vie$ of the line ) and at the ase line then

pro!ect another numered lines ac;$ard from si580 to

one*0 using a compass

<. (onnect the points to create vertical parallel lines

using a ruler



9. +etermine the circumference y measuring the lines

created y the numered parts from the half circle

*7. =rom the ase line set 1.3 cm up$ard and pro!ect to the

stretch-out pattern

**. (hec; the numer one *0 and seven:0 of the 1.3cmthen connect to the numer four40 form the ase line

*ote te n"m,er 2=6 i%e 3=5 an' 1=#

*1. Measure the distance of the numer 1 or 8 from thease line of the o!ect then pro!ect it to the stretch out

pattern for the dra$ing of the figure



*/. +o the same process $ith numer / or 3

*4. After pro!ecting their distance connect the line

from * to 4 # 4 to :# : to 4 and 4 to *

*3. Lastly# dar;en slo$ly the o!ect and the pattern

dra$ing then erase the unnecessary lines.
