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. WebA triangle is a basic polygon with three sides and three vertices. Since it has three sides, it has three interior angles.
