Question

3. Vocabulary Suppose △MNP ∼△RST. How can you identify corresponding parts?

Answer 1

Similar triangles may or may not have congruent sides, but the ratio of the corresponding sides will always be congruent.

(3) Corresponding sides of △MNP and △RST

Given that △MNP ∼△RST.

This means that, the corresponding sides are:

• MN and RS
• MP and RT
• NP and ST

(4) The equal measures

Given that △ABC ∼△TUV

This means that, the corresponding angles are equal, but corresponding sides are not.

So, the equal measures are:

• (a). the measures of ∠A and ∠T
• (c). the ratios of the sides BC/UV and AC/TV

The unequal measure is:

• (b). the perimeters of the two triangles

(c) Scale mapping

The scale mapping is given as:

$Ratio = 1\ in : 100\ mi$

The above scale means that 1 inches on the scale represents 100 miles of the actual distance.

Take for instance, 5 inches would represent 500 miles.

500 is 5 times 100

Hence, the actual distance between two towns 100 times the map distance between the two towns
