WebPolygons are named according to the number of sides and angles they have. The most … WebDefinition: Diagonal. We say can see a point in a polygon P if the segment is fully contained in P. A diagonal then, is the line segment joining two vertices that can see each other.. Lemma 2. Every polygon P has at least one diagonal. Proof. Let be a strictly convex vertex of a polygon P. The existence of such a vertex was established by lemma 1. WebThe polygon has three sides so we are looking at a triangle. 2 Determine the size of the angles/side lengths within the polygon. Angles in a triangle total 180^ {\circ} 180∘ and so the missing angle is equal to 180 - (70+55)=55^ {\circ} 180 − (70 + 55) = 55∘. 3 Recognise the other properties of the polygon. greencastle windows
