Answer:

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.

Answer: the angle on the end of the length should have a square.

Step-by-step explanation: In math and geometry, a square around an angle shows 90 degrees, which is another meaning of a right angle. If a triangle or square has a right angle of 90 degrees, it will show it by having the square in the vertice.

Answer:

AN = 16 units

Step-by-step explanation:

So we can use the fact that $\frac{AN}{FN} =\frac{OR}{FR}$

Since this is an isosceles triangle, segments FO and FR are both equal to 7

Manipulating the equation above to solve for AN we have $AN = \frac{(FN)(OR)}{FR}$

Substituting in the known values we have $AN=\frac{(10)(11.2)}{7} =16$
