Flexi Answers Are Alternate Interior Angles Equal Ck 12 Similarly, @$\begin{align*}\angle 4\end{align*}@$ and @$\begin{align*}\angle 6\end{align*}@$ are alternate interior angles. the alternate interior angle theorem states that, if two parallel lines are cut by a transversal, then alternate interior angles are congruent. to learn more about theorems related to lines and angles, click here!. When two parallel lines are cut by a transversal, two pairs of alternate interior angles are formed. to solve alternate interior angles, remember that they are equal when the lines are parallel. so, if you have two parallel lines cut by a transversal, the alternate interior angles will be equal. in the diagram below, @$\begin{align*}\angle 3.
Flexi Answers What Are Alternate Interior And Exterior Angles Ck Flexi says: alternate interior angles are two angles that are on the interior of @$\begin{align*}l\end{align*}@$ and @$\begin{align*}m\end{align*}@$, but on opposite sides of the transversal. alternate interior angles theorem: if two parallel lines are cut by a transversal, then the alternate interior angles are congruent. Alternate interior angles are two angles that are on the interior of l and m, but on opposite sides of the transversal. alternate interior angles theorem: if two parallel lines are cut by a transversal, then the alternate interior angles are congruent. if l | | m, then ∠1 ≅ ∠2. List the pairs of alternate interior angles: alternate interior angles: ∠ 4 and ∠ 5, ∠ 3 and ∠ 6. review. is the angle pair ∠ 6 and ∠ 3 congruent, supplementary or neither? give two examples of alternate interior angles in the diagram: for 3 4, find the values of x. for question 5, use the picture below. find the value of x. Solution: according to the interior angle theorem, alternate interior angles are equal when the transversal crosses two parallel lines. thus, (4x – 19)° = (3x 16)°. 4x – 3x = 16 19. x = 35°. now, substituting the value of x in both the interior angles expression we get, (4x – 19)° = 4 x 35 – 19 = 121°. (3x 16)° = 3 x 35 16.

According to the image below: alternate interior angles are: ∠3 and ∠6, ∠4 and ∠5. alternate exterior angles are: ∠1 and ∠8, ∠2 and ∠7. for example: let us try to spot alternate interior angles in the given figure. remember the lines do not have to be always parallel for alternate angles to be formed. Alternate interior angles examples. example 1: find the measure of angle x in the following figure if the two lines are parallel and they are crossed by a transversal. solution: by the alternate interior angles theorem, x and 20° are the alternate interior angles. hence, they are equal.
