if two lines intersect each other then the vertical opposite angles are eqal or
prove that: angles opposite to eqal sides of an inosceles triangle are equal​

Answer 1

Answer:

A pair of vertically opposite angles are always equal to each other. Also, a vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees. For example, if two lines intersect and make an angle, say X=45°, then its opposite angle is also equal to 45°.
