If abcde ≅ lmnpq, then how many pairs of corresponding parts are in the figures?

10

Step-by-step explanation:

Given: ABCDE ≅ LMNPQ

We know that if any two polygons are congruent then their corresponding sides and angles are congruent.

Since, the given polygons' name has 5 letters, therefore they must have 5 vertices i.e. 5 angles (∠A≅∠L, ∠B≅∠M, ∠C≅∠N, ∠D≅∠P, ∠E≅∠Q) and 5 sides (AB=LM, BC=MN, CD=NP, DE=PQ, AE=LQ )

Therefore, the number of pairs of corresponding parts are in the figures=5+5=10

C. because when you reduce 6:4(you can divide by 2) you get 3:2
