WebAs angles in a triangle total 180° 180°, angle ABC = 180 - (70+40) = 70° ABC = 180 − (70 + 40) = 70°. 2 Use the appropriate circle theorem to find the subtended angle. As angles in the same segment are equal and AC AC is a chord shared by the points B B and D D within the same segment, the angle ADC ADC = angle ABC = 70° ABC = 70°. Web17 nov. 2024 · In Figure 1.5.1 we see an angle θ in QI which is rotated by 90 ∘, resulting in the angle θ + 90 ∘ in QII. Notice that the complement of θ in the right triangle in QI is the same as the supplement of the angle θ + 90 ∘ in QII, since the sum of θ, its complement, and 90 ∘ equals 180 ∘. This forces the other angle of the right triangle in QII to be θ. Web13 jan. 2024 · Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well. Half of 360 ° is 180 °. For example, the sum of the angles of the quadrilateral below is 360 ° because it consists of four 90 ° angles. The pink triangle is half of this, therefore the sum of its angle measures should also be half ( 180 °). birthday party craft ideas
