To determine

To prove:

The statement RTVT=RSVU if the sides RS and UV are parallel, RS¯UV¯.

Explanation

Definition:

AA:

If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

CSSTP:

Corresponding sides of similar triangles are proportional.

Description:

Given that RSÂ¯âˆ¥UVÂ¯.

The given figure is shown below.

Figure

From the given figure, it is observed that the sides RS and UV are parallel, RSÂ¯âˆ¥UVÂ¯.

If two parallel lines are cut by a transversal, then the alternate interior angles are congruent.

Therefore, âˆ Râ‰…âˆ V and âˆ Sâ‰…âˆ U.

The above mentioned AA definition, the two triangles RST and TUV are similar since the two angles of one triangle are congruent to two angles of another triangle. Hence, Î”RSTâˆ¼Î”TUV

From the definition of CSSTP, corresponding sides of similar triangles are proportional
