At times, in geometry, the pair of angles are used. x = 120° – 80°. Square: (image will be uploaded soon) In the figure of a square given above, there are many examples of complementary angles and supplementary angles and we can elaborate it as, the angle GBO and its adjacent angle FBO can be combined to form the angle … NOT Adjacent Angles. below, four angles are formed. For example, adjacent angles of a parallelogram are supplementary, and opposite angles of a cyclic quadrilateral (one whose vertices all fall on a single circle) are supplementary. Adjacent angles shares a common side. Apart from the above-mentioned angles, there are other types of angles too. There are various kinds of pair of angles, like – supplementary angles, complementary angles, adjacent angles, linear pair of angles, opposite angles, etc. ∠PHI∠PHI and ∠PHU∠PHU 4. adjacent example sentences.
