Question

How to solve please

Answer 1

Ans. We need to find the value of x and y in the figure given below and then prove that

From the figure, we can conclude that

(Vertically opposite angles), and

form a pair of linear pair.

We know that the sum of linear pair of angles is.





.

From the figure, we can conclude thatform a pair of alternate interior angles corresponding to the lines AB and CD.

Therefore, we can conclude that.

Let's see the properties used here :

☛ ᏞᏆNᎬᎪᎡ ᏢᎪᏆᎡ ᎪXᏆᎾᎷ - If a ray stands on a line, then the sum of the two adjacent angles so formed is 180° and vice versa. This property is called as the linear pair axiom.

☛ ᏢᎡᎾᏢᎬᎡᎢY - If two lines intersect each other, then the vertically opposite angles are equal.
