Complete the proof showing why vertical angles are congruent WITHOUT using the vertical angles theorem. Will Give Brainlist

Explanation:

Statement . . . . Reason

1. ∠1 and ∠2 are a linear pair; ∠2 and ∠4 are a linear pair . . . . given

2. ∠1+∠2 = 180°, ∠2+∠4 = 180° . . . . definition of linear pair

3. ∠1+∠2 = ∠4+∠2 . . . . substitution property of equality

4. ∠1 = ∠4 . . . . subtraction property of equality

In words: angles supplementary to the same angle are congruent.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

exactly you go it
