Therefore we have Solving this equation, we get x = 5 Substituting, angle 1 has measure 4(5) = 20º and the same is true of angle 2: 2(5) + 10 = 20º We use this information to find angle 3 which is supplementary to both angles 1 and 2. True or False? x + 4 = 2x-3 true. Example: Find angles a°, b° and c° below: Because b° is vertically opposite 40°, it must also be 40° A full circle is 360°, so that leaves 360° − 2×40° = 280° Angles a° and c° are also vertical angles, so must be equal, which means they are 140° each. NOT Adjacent Angles. Picture 3 is another picture of vertical angles. Two triangles, ABC and A′B′C′, are similar if and only if corresponding angles have the same measure: this implies that they are similar if and only if the lengths of corresponding sides are proportional. Two angles whose sides are opposite rays are called _____ angles… Answer: (d) When a transversal cuts two lines such that pairs of interior angles on the same side of the transversal are complementary, then the lines have to be parallel Question 31.
