∠2 = ∠3 | Given

∠1 + ∠2 = 180 | Supplementary Angles Postule (If two angles are adjacent and                  ∠3 + ∠4 = 180|                                                        linear, they're supplementary)

∠1 + ∠2 = ∠3 + ∠4 | Transitive property

∠1 + ∠3 = ∠3 + ∠4 | Substitution property

∠1 = ∠4 | Subtraction Property

∠2 = ∠3 | Supplementary Congruent Theorem

Since the slope of a vertical line is undefined, is it possible for vertical lines to be parallel.(Explain)
Sedbober [7]

Yes the slope of a vertical line is parallel.

Parallel lines never intersect each other.

Y-axis is a vertical axis cartesian coordinate plane.

All vertical lines would be parallel to y-axis.

Because all vertical lines would have same slope, that is undefined slope.

Therefore, <em>all vertical lines would be parallel lines.</em>

So, we can finally say that it is possible for vertical lines to be parallel.

two opposite sides of a square are increased by 5 cm to form a rectangle. if the rectangle has a perimeter of 70 cm's, what was
Mrac [35]
This could be done in two different ways. One is by first knowing the perimeter of rectangle, which in this case is 70, then identifying the increase of the opposite side, increased by 5 which is equal to 10 overall. After that let us establish a working equation, square = rectangle - 10. By that let us substitute the value, square = 70 - 10; square = 60 cm. Then remember that square has four equal side, so square = 60 divided by 4 = 15. So the original side of square is 15 cm.
