Notes on lines and angles
WebMar 26, 2024 · Example - 2 From the figure illustrated below find the value of ∠MOP, if ∠MOQ or ∠y=100°. Now sum of angles ∠MOP and ∠MOQ is 180°, using this piece of information, we can easily find the value of 2x or ∠MOP. As, ∠MOP + ∠MOQ = 180°. So, 2x + 100 = 180°. On solving the above equation, you will get 2x or ∠MOP as 80°. Web4. If two lines intersect, then the vertically opposite angles are equal. 5. A line which intersects two or more given lines at distinct points, is called a transversal of the lines. 6. Two angles on the same side of a transversal are known as corresponding angles if both lie either above the two lines or below the two lines. 7.
