Question

29. If two lines intersect each
other then the vertically
opposite angles are-​

Answer 1

Answer:

When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other. ... When two lines meet at a point in a plane, they are known as intersecting lines.

Answer 2

Answer:

When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles.

Step-by-step explanation:

If two lines intersect each other, then the vertically opposite angles are equal. Theorem 6.1 : If two lines intersect each other, then the vertically opposite angles are equal. In the statement above, it is given that 'two lines intersect each other'. So, let AB and CD be two lines intersecting at O as shown in Fig.
