Ice on a lake gets thicker as long as the temperature is below freezing. On a certain lake it
took 8 days for the ice to reach a thickness of 3 inches.
(a) At what rate was the ice growing over these 8 days in inches per day? Do not round your
decimal answer
(b) Ice is safe to walk on when it is 10 inches thick. Would this ice be safe after 3 weeks if it
grew at the rate in (a)?
(c) The ice will stop growing if it reaches a thickness of 1.5 feet. At the rate in (a), how many
days of freezing would this take? First, think about how many inches 1.5 feet represents.

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)
