Answer: D: Corresponding parts of congruent triangles are congruent
Step-by-step explanation:
If two triangle are congruent using postulate of theorems of congruence then their corresponding parts are congruent by CPCTC rule.
The CPCTC rule says that if two triangles are congruent then their each corresponding part whether angles or sides must be equal.
Here if triangle abc= def by side-side-side triangle congruence theorem,
then b=e [which is a corresponding part of both triangles] by Corresponding parts of congruent triangles are congruent.
Answer: 1527
Step-by-step explanation:
Total Area = 7500 ft^2
Area covered by one student = Area of one circle
= π*r^2
r = radius of circle = 2.5/2 = 1.25 ft
Area covered by one student = π*1.25^2 = 4.91 ft^2
Number of students who can fit into total area = Total Area/Area covered by one student
Number of students who can fit into total area = 7500/4.91 = 1527.49
Hence the answer is 1527 students
