I hate to sound rude but are you trying to find ..??
If we are talking about degrees they should equal 180
Answer:
(3,9)
Step-by-step explanation:
So I drew a right triangle with the line segment A(1,-9) to C
as the hypotenuse. This line segment does contain point B(2,0). This is shown in the picture.
We want to find a point C so that AB to BC has a ratio of 1:1. So this means B is the midpoint really.
So if we averaged the endpoints of the line segment it would equate to point B.
That is:
and 
Multiply both sides by 2:
and 
The first equation can be solved by subtracting 1 on both sides giving 
.
The second equation can be solved by adding 9 on both sides giving
.
Point C is (3,9).

If two triangles are congruent, then the six <u>corresponding</u> parts are congruent
<u><em>Explanation:</em></u>
When writing congruency, the order of writing the letters is extremely important. This is because each side/angle in the first triangle would be congruent to its corresponding side/angle in the other triangle.
<u><em>Example:</em></u>
<u>If triangle ABC is congruent to triangle DEF, then:</u>
angle A = angle D
angle B = angle E
angle C = angle F
AB = DE
BC = EF
AC = DF
