Answer» ANSWER:DETERMINE whether each pair of SOLIDS is similar,congruent, or neither. If the solids are similar,state the scale factor.1. SOLUTION: Ratio of radii: Ratio of heights: The RATIOS of the corresponding measures are equal,so the solids are similar. The scale factor is 4:3. Sincethe scale factor is not 1:1, the solids are notcongruent.ANSWER: similar; 4:32. SOLUTION: The base of ONE pyramid is a quadrilateral, while thebase of the other is a triangle, so they are neithercongruent nor similar. |
