Question

1. to use sas similarity, ab and cb must be dropdown with options: greater than, less than, proportional to db and eb, respectiv

Explanation:

The SAS (Side - Angle - Side) similarity criterion for triangles states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar. So, for using SAS similarity, the sides AB and CB (of one triangle) must be proportional to sides DB and EB (of the other triangle). "Greater than" and "less than" do not relate to the SAS similarity condition as it is about the proportionality of sides, not their magnitude comparison.

Answer:

proportional to
