Lines and angles

Question 1

Axiom 3

Answer 1

If a transversal intersects two lines ,then each pair of corresponding angles are equal

Question 2

Theorem 2

Answer 2

If a transversal intersects two parallel lines,then each pair of alternate interior angles are equal

Question 3

theorem 4

Answer 3

if a transversal intersects two lines, then each pair of co- interior angles are supplementary

Question 4

theorem 5

Answer 4

Lines which are parallel to the same line are parallel to each other

Question 5

theorem 7

Answer 5

the sum of the angles of a triangle is 180 degree

Question 6

theorem 8

Answer 6

if the side of a triangle is produced, then the exterior angle so formed is equal to the sum of opposite interior angles.
