Solution: `x = 105°` (Vertically opposite angles)Similarly, `y = 75°` (Vertically opposite angles). Similarly, the angles ∠ D O A and ∠ C O B are also called as vertically opposite angles. Answer (i) 90° (ii) 180° (iii) supplementary (iv) linear pair (v) equal (vi) obtuse angles 14. So we’ve answered the first part of the question, and now we need to go on and answer the second part of the question, which asked us to find the value of , or, in other words, solve this equation. When the sum of the measure of two angles is 180 degree, the angles are called supplementary angles. Recognise angles where they meet at a point, are on a straight line, or are vertically opposite, and find missing angles Use our Year 6 planning resources to effectively teach the 2014 National Curriculum aim 'recognise angles at a point, on a straight line or vertically opposite and find missing angles'. Question 5. The value of ∠AGE is: a) 120° b) … Thus, the vertically opposite angles are formed geometrically.
