Answer:
1) Two concepts that are related but not the same are supplementary angles and complementary angles. The difference is their sum. Supplementary angles are two angles whose measures sum to a 180 degrees and complementary are the sum have to add up to 90 degrees.
2)Whenever two lines intersect, they form two pairs of vertical angles. Vertical angles have a common vertex, but they are never adjacent angles. Finally, vertical angles are always congruent.
3)The sum of the lengths of any two sides of a triangle is greater than the length of the third side. If you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. If that is not true, then it is not possible to construct a triangle with the given side lengths.
4) The area is 201.06
The circumference is 50.27
[don't really know how to explain so here are the formulas, (hope it helps)
C(circumference)= 2 x pi x r(radius)
A(area)= pi x r(radius)^2
5) Unique Triangles are Triangles that do not have an equivalent. This means there is not another triangle that has the exact dimensions or shape. The sets of facts or conditions that you need to know to create an unique triangle.
