Arc lengths
Anna is determining the length of arc ED by using the ratio AB/BC=ED/EF.. What must be true before using the ratio?
1 answer
Before using the ratio, Anna must first ensure that triangles ABC and DEF are similar, meaning that their corresponding angles are equal and their corresponding sides are proportional. This ensures that the ratio AB/BC is equal to the ratio ED/EF.
