Theorem 6 2 Class 9 Alternate Interior Angles Are Equal

Theorem 6 2 Class 9 Alternate Interior Angles Are Equal Theorems Transcript. theorem 6.2 : if a transversal intersects two parallel lines, then each pair of alternate interior angles are equal. given : two parallel lines ab and cd. let ps be the transversal intersecting ab at q and cd at r. to prove : each pair of alternate interior angles are equal. i.e, bqr = crq and aqr = qrd proof : first, we will. The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs. these angles are called alternate interior angles. in the above given figure, you can see, two parallel lines are intersected by a transversal. therefore, the alternate angles inside the parallel lines will be equal.

Theorem 6.2: if a transversal intersects two parallel lines, then each pair of alternate interior angles is equal. theorem 6.1 theorem 6.3 prerequisite this is one of the most easy to prove and widely used theorem to prove other theorems…. 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. 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.
