TRUE OR FALSE Directions: Write T if the statement is correct and F if it is incorrect. Write your answer on the space provided before each number. 1. The PRODUCT of the EXTREMES equals the product of the MEANS. 2. When quantities are of different kinds, the comparison of the quantities that consider the units is called rate. 3. a: bande:d is read as "a is to base is tod". 4. Fundamental theorem of proportionality states that if a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally. 5. Alternation Property states that. 1/ = . then = = =:w = 0,x # 0,y # 0,2# 0 6. AAA Similarity Theorem states that. if the three angles of one triangle are congruent to the three angles of another triangles, then the two triangles are similar. 7. In the proportion 2; x = 3:9, x = 2 8. If the ratios a: bande: dare equal, then we write ach-cad or " =(where band d are nonzero). 9. SSS Similarity Theorem states that. Two triangles are similar if the corresponding sides of two triangles are in proportion. 10. Vertical angles are congruent.
