In △abc, m∈ ac and n∈ bc . prove that mn ∥ ab , if: am/cm =bn/cn

See proof below

Step-by-step explanation:

1. Consider in triangles ABC and MNC the ratio

Since then

2. Consider in triangles ABC and MNC the ratio

Since then

3. You are given that

then

4. The previous statement gives you that triangles ABC and MNC are similar (they have two pairs of proportional sides and common angle C). Similar triangle have congruent corresponding angles. Hence,

First pair of angles form corresponding angles at lines MN and AB and transversal BC and second pair of angles form corresponding angles at lines MN and AB and transversal AC. Since corresponding angles are congruent, the lines AB and MN are parallel.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
