Answer:

The angle bisector completed incorrectly is the angle bisector with the heading "Example 2"

How it is known that the bisector with heading "Example 2" was completed incorrectly is the difference between the length of the intersection of the two arcs on the two lines that form the angle which is to be bisected

The angle bisector is constructed from the intersection of the arcs drawn from the two arcs intersecting the lines forming the angle, therefore, they need to be equidistant from the point B in order to construct the line passing through midpoint of the angles

Step-by-step explanation:

Hi there! First thing I want to say is that I will have a photo attached to this problem. If you don't see it or need any more clear explanation, please don't hesitate to reach out! Anyways, I will go step by step for this problem and also include a definition.

Okay, what we have here is a right triangle, which has a 90 degree angle. And we have two sides and want to find the other side. With this problem, we will use the pythagorean theorem. The pythagorean theorem is an equation or formula that helps someone to find a side of a 90 degree right triangle, when two sides are presented.

Formula: a² + b² = c²

a would be the height of the triangle, b would be the length, and c is the hypotenuse of the triangle.

What we have so far is b and c. b is 3 and c is 5. So with that in mind we will replace b and c with the numbers we are given. And then solve from there...

a² + b² = c²

a² + 3² = 5²

a² + 9 = 25

a² = 16

$\sqrt{a^{2} }$ = $\sqrt{16}$

a = 4

There you go! And you can always go back and check your answer! I hope this helped, if not please ask and don't be afraid! And I again have attached a picture of the work! Have a great day!
