The side of triangle ABC is AB = 18 , of triangle RST is ST = 5 , RT = 3 .
What is a Triangle ?
A triangle is a polygon with three sides , three vertices and three angles.
It is given that
Triangle ABC and RST
BC = 15, AC = 9, and RS= 6.
the lengths of the missing sides of AABC and
ARST
When two triangles are similar their sides are proportional and it is given that the scale factor is 1/3
6:z = 1:3
z =18
y:9 = 1:3
y =3
x:15 =1:3
x =5
Therefore the side of triangle ABC is AB = 18 , of triangle RST is ST = 5 , RT = 3 .
The triangles sketch is attached.
