Supplementary angles definition: They add up to 180°

There are several ways to prove a parallelogram:

1. Opposite sides theorem converse

2. Opposite angles theorem converse

3. Parallelogram diagonals theorem converse

4. Parallel congruent sides theorem

∠P + ∠Q = 180° --1

∠P + ∠S = 180° --2

1: ∠P = 180° - ∠Q

Sub 1 into 2:

180° - ∠Q + ∠S = 180°

180° + ∠S = 180° + ∠Q

∠S = ∠Q

Or you can try saying the opposite sides are parallel, since they are interior angles and those are straight lines

Similar Triangles
NeTakaya

Answer:

5.3 ft

Step-by-step explanation:

Because CD corresponds to BC, the scale factor from triangle ABC to triangle CDE, is 7/8. Now, DE corresponds to AB, so to get DE, we must multiply the value of AB by 7/8. 6 times 7/8 is 5.25, and rounding to the nearest tenth of a foot, the value of DE is 5.3.

Write an equation in slope-intercept form that passes through each pair of points. (0, 1) (-3, 1)
lina2011 [118]

Answer:

y =  \frac{0}{ - 3}  + b

Step-by-step explanation:

Slope intercept formula is y=mx+b

(m) is slope

(b) is the y intercept

We'll find slope first.

slope formula is

\frac{y2 - y1}{x2 - x1}

y2 and x2 are the y and x values of the second equation and y1 and x2 are the y and x values of the first equation.

So we just put the given values into our equation.

\frac{1 - 1}{ - 3 - 0}

Simplify

\frac{0}{ - 3}

Now we put this into our y=mx+b

y=0/-3x+b

now we need the (b)

to do this we take the values of one of the coordinates (doesn't matter which) and replace the (y) and (x) in our equation with them.

y =  \frac{0}{ - 3} x + b

1 =  \frac{0}{ - 3} (0) + b

Solve

1=0+b

b=1

Put this in our formula

y =  \frac{0}{ - 3}  + 1

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
