Question

5. Use similar triangles to find side lengths.

Answer 1

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.
