You prove the base angles are congruent by constructing the angle bisector through the vertex angle of an isosceles triangle. By constructing the angle bisector, we designed two congruent triangles and then used CPCTC to show that the base angles are congruent.
Step-by-step explanation:
Answer:
R is a partial order
Step-by-step explanation:
The relation is reflexive
That is to say, aRa
The relation is antisymmetric, if aRb and bRa, then a=b
The relation is transitive, if aRb and bRc, then aRc
Answer:
The answer is
<h2>21.45 g/cm³</h2>
Step-by-step explanation:
The density of a substance can be found by using the formula

From the question
mass of platinum = 214.5 g
volume = 10 cm³
It's density is

We have the final answer as
<h3>21.45 g/cm³</h3>
