  • May 29, 2018 · Theorem 6.8 :- If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles. Given :- A PQR ,QR is produced to point S. where ∠PRS is exterior angle of PQR. To Prove :- ∠4 = ∠1 + ∠2 Proof:- From
  • Classify the relationship between each pair of angles as alternate interior, alternate exterior, corresponding, or consecutive interior angles. 5. ∠2 and ∠10 6. ∠7 and ∠13 . 7. ∠9 and ∠13 8. ∠6 and ∠16 . 9. ∠3 and ∠10 10. ∠8 and ∠14

  • The interior angles of a shape are the angles inside the shape. The exterior angles are the angles formed between a side-length and an extension. Rule: Interior and exterior angles add up to 180\degree 180°.
  • Triangle has three sides and formula to find out the measure of each interior angle: 180( n - 2)/n. Measure of exterior angle: 180 - measure of each interior angle. Here n is number of sides of the given polygon, n = 3. Measure of each interior angle = sum of all angles ÷ n. So, by using formula: 180( n - 2)/3 = 180( 3 - 2)/3 = 180 × 1 ...

Oct 02, 2015 · The vertically opposite angles are equal. The alternate interior angles are equal. The alternate exterior angles are equal. The pair of interior angles on the same side of the transversal is supplementary. We can say that the lines are parallel if we can verify at least one of the aforementioned conditions. Let us take a look at some examples.

The same thing applies for same side exterior angles, so I'm going to erase this and write exterior. But what am I talking about same side exterior, well if I erase these marks exterior means outside of the parallel lines. So if I chose angle two the same side exterior would not be 6 cause 6 is in between the parallel lines but it will be 7.
