WebMar 26, 2016 · You can use the following theorems to prove that lines are parallel. That is, two lines are parallel if they’re cut by a transversal such that Two corresponding angles are congruent. Two alternate interior angles are congruent. Two alternate exterior angles are congruent. Two same-side interior angles are supplementary. WebBy setting them equal to each other, you can find the value of x. To set them equal, what you need to do is place the equations on either side of an equal sign. (8x-184=4x-148) By doing this, you indicate that the sides are equivalent. Then, you solve for x by, in this example, adding 184 to negative 148. WebI think I have a correct proof now. Proof by contradiction: Assume to the contrary that two lines parallel to the same line are not parallel to each other. Without loss of generality, assume line m and line n are parallel to a line l, but m and n are not parallel to each other.

"WebImagine two lines that intersect each other. That gives you four angles, let's call them A, B, C, D (where A is next to B and D, B is next to A and C and so on). There are two pairs of vertical angles; A = C and B = D. They only connect at the very tip of the angles. There are four linear pairs. Linear pairs share one leg and add up to 180 degrees.
