Webif two lines are both intersect both a third line, so lets say the two lines are LINE A and LINE B, the third line is LINE C. the intersection of LINE A with LINE C creates 4 angles around the intersection, the same is also true about the LINE B and LINE C. For example parallel lines have the same slope and different y intercepts, while a … Now, we also know that AB and CD are parallel. So this line right over here, this … WebAnswer (1 of 8): a cross b = a * b *sin α, α being the angle between the vectors a and b. Since they are parallel α=0 or α=π. In both cases sin α = 0; therefore the cross product …

WebExample 8. If ∠ 1 ∘ and ∠ 8 ∘ are equal, show that ∠ 4 ∘ and ∠ 5 ∘ are equal as well. Solution. The angles ∠ 1 ∘ and ∠ 8 ∘ are a pair of alternate exterior angles and are equal. Recall that two lines are parallel if its pair of alternate exterior angles are equals. Hence, A B ― and C D ― are parallel lines. WebSolution. For two vectors ( a + b) and ( a - b ) to be parallel their cross product need to vanish ie. ==> 2 b × a = 0; or b × a = 0. Or this implies that vectors a and b are parallel … WebParallel line through the given point Perpendicular line through the given point Settings: Hide graph Hide steps Find approximate solution Calculate examples example 1: Find the equation of the line that is parallel to and passes though the point . example 2: Find the equation of the line that is perpendicular to and passes though the point . har section 3-122-81
