WebVertical ∠’ s are ≅. ∠’s that form a linear pair are supplementary (add up to 180°) ∠’ s that form a circle add up to 360° When ∥ lines are cut by a transversal, all acute ∠’ s are ≅ and all obtuse ∠’ s are ≅. Triangles: The three ∠’ s of a ∆ add up to 180° An exterior ∠ is equal to the sum of the two WebDec 26, 2009 · Suppose the diagonals meet at a point X.AB is parallel to DC and BD intersects themTherefore, angle ABD ( = ABX) = BAC (= BAX)Therefore, in triangle ABX, the angles at the ends of AB are equal => the triangle is isosceles and so AX = BX.AB is parallel to DC and AC intersects themTherefore, angle ACD ( = XCD) = BDC (= XDC)Therefore, … flag wivenhoe
