Explain how to find m∠2 if m∠1 = 135. DAB is a right angle. Linear pair is a pair ofadjacent angleswhere non-common side forms a straight lineSo, In a linear pair, there are two angles who haveCommon vertexCommon sideNon-common side makes a straight line or Sum of angles is 180°Linear pairLinear pair is a pair of adjacent angles where non-common side forms a So, the angle measures are 125°, 55°, 55°, and 125°. In mathematics, a duality translates concepts, theorems or mathematical structures into other concepts, theorems or structures, in a one-to-one fashion, often (but not always) by means of an involution operation: if the dual of A is B, then the dual of B is A.Such involutions sometimes have fixed points, so that the dual of A is A itself. Other types of angles include vertical angles and congruent angles. The 5′ ends of these duplex DNAs project as single-strands beyond 3′ ends. Such angle pairs are called a linear pair.. Angles A and Z are supplementary because they add up to 180°.. Vertical angles: When intersecting lines form an X, the angles on the opposite sides of the X are called vertical angles. Vertical angles are two angles whose sides form two pairs of opposite rays. LINES AND ANGLES 93 Axiom 6.1 : If a ray stands on a line, then the sum of two adjacent angles so formed is 180°. Angles can be classified base upon the measure: acute angle, right angle, obtuse angle, and straight angle. The sum of the measures of two _?_ angles is 180. iii.

Two angles that share a common vertex and a common ray (side), but that do not share any interior points. A student designed the stationery border shown here. For two angles to be adjacent, they only have to share a leg, which puts no restrictions on whether the non-common legs form a straight line or not. The angle with measure 125 and ∠5 are supplementary. So, the sum of their measures is, AED  =  (3x + 5)°  =  (3 • 40 + 5)°  =  125°, DEB  =  (x + 15)°  =  (40 + 15)°  =  55°, AEC  =  ( y + 20)°  =  (35 + 20)°  =  55°, CEB  =  (4y - 15)°  =  (4 • 35 - 15)°  =  125°, So, the angle measures are 125°, 55°, 55°, and 125°. 19.
