14...or as my dad would say, 10
The third side would be either 5 or 8,as an isosceles triangle has 2 equal sides.
An isosceles triangle has two sides that are equal length, and the other side would be a different length. A right triangle could be an isosceles triangle. On the other hand, a scalene triangle has all of its sides different lengths.
A triangle with 1 side only measuring 4 inches can have two of its angles measuring 55° and 35°. The side would be either the hypotenuse or one other other sides of a right angled triangle. NOTE : A triangle with two of the three sides measuring 4 inches cannot have one of its angles measuring 55° and one other measuring 35° as the two sides of equal length would define it as an isosceles triangle. Therefore two of its angles are equal. If the two equal angles measured 35° each, then the third angle would equal 110°. If the two equal angles measured 55° each then the third angle would equal 70°. A triangle with all three sides measuring 4 inches has all three angles measuring 60° . It is an equilateral triangle.
Never, there are no true "opposite sides" on a triangle as each side intersects the other two at a point. Were two of the lines parallel, the triangle would be missing a point and would not be a closed shape.
That is the definition of a triangle. If it did not have three sides it would not be a triangle. If it did not have three angles, it would not be a triangle.

This would be an isosceles triangle.
They are triangles. An isosceles triangle has two sides that are equal length, and the other side would be a different length. A right triangle could be an isosceles triangle. On the other hand, a scalene triangle has all of its sides different lengths.

YES For a triangle to exist then the sum of any two sides must be greater than the third side. 25 + 46 = 71 > 65 25 + 65 = 90 > 46 46 + 65 = 111 > 25 If the sum of two sides equalled the third side then you would have two straight lines laid on top of each other. If the sum of two sides is less that the third side then it impossible to create three vertices to enable a triangle to be formed.
You are a scalene triangle. If you were to have two of the same sides similar, you would be an isoceles triangle. If you were to have all of your sides the same, you would be an equilateral triangle.
No TRIangle can have two equal sides it would be an angle. A triangle with 2 equal sides is called an isosceles triangle.
if the triangle was an equilateral triangle, you would have been able to just multiply 45 with 3... but if the triangle was some other kind of triangle, you would have to know the other sides
