Question

The ratio of two corresponding sides in similar figures is called the scale factor. Scale factor =

ℎ / ℎ If one shape can become another using

Resizing then the shapes are Similar. If two similar triangles have a scale factor of a: b. Which

statement regarding the two triangles is true?

(i)The ratio of their perimeters is 3a : b(ii)Their altitudes have a ratio a:b

(iii)Their medians have a ratio

2

: b (iv)Their angle bisectors have a ratio a2

: b2​

Answer 1

Answer:

When two triangles are similar, the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles. In Figure 1 , Δ ABC∼ Δ DEF. Figure 1 Similar triangles whose scale factor is 2 : 1.
