Construction:
Step
1
: Draw base
X
Z
=
9.5
c
m
with a ruler.
Step
2
: Place the compass on point
X
and measure an arc with length of the compass as
X
Y
=
7.5
c
m
.
Step
3
: Place the compass on point
Z
and measure an arc with length of the compass as
Y
Z
=
8.5
c
m
.
Step
4
: Mark the intersection point of the arcs in steps
2
and
3
as point
Y
and draw lines joining
X
−
Y
and
Z
−
Y
.
△
