VERTICALLY OPPOSITE ANGLES ARE IN MEASURE
Answers
vertically opposite angles are equal in measure
★ Vertically opposite angles are equal in measure.
Some more to know :-
☞ 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.
☞ 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°. And the angle adjacent to angle X will be equal to 180 – 45 = 135°.
- Intersecting Lines
When two lines meet at a point in a plane, they are known as intersecting lines.
- Non - intersecting lines
When the lines do not meet at any point in a plane, they are called parallel lines.
