Question

how many axiom are there in class 9th?​

Answer 1

Answer:

Euclidean Axioms

Here are the seven axioms given by Euclid for geometry. Things which are equal to the same thing are equal to one another. If equals are added to equals, the wholes are equal. If equals are subtracted from equals, the remainders are equal.

Explanation:

Axiom 1

If a ray stands on a line, then the sum of two adjacent angles so formed is 180°.

Axiom 2

If the sum of two adjacent angles is 180°, then the non-common arms of the angles form a linear pair.

Axiom 3

Corresponding Angle Axiom: If a transversal intersects two parallel lines, then each pair of corresponding angles are equal.

Converse: If a transversal intersects two parallel lines such that a pair of corresponding angles is equal then the two lines are parallel.
