Thomas is researching locations to live after high school and asks his family members about the number of different places they have lived. let a be the set of the number of places where nine of thomas' family members have lived after high school.

thomas forgot that his uncle traveled with the military and has lived in 15 different places since high school. let b represent the set of the number of places where all ten of his family members, including his uncle, have lived after high school.

select the true statement.

a.
the interquartile range of a is 1.5 less than the interquartile range of b.
b.
the mean of b is greater than the mean of a.
c.
the mean of b is the same as the mean of a.
d.
the interquartile range of a is 0.5 more than the interquartile range of b.

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
