A sorry I can't see the image
Let us consider the image on the left that is the image in which 1 and 2 , 3 and 4 are connected as image 1 and the other as image 2.
1. All Vertices are connected by the least amount of edges. True
2. Vertex 1 and 2 are not connected. This is false for image
1 and true for image 2
3. Vertex 3 and 4 are not connected. This is false for image
1 and true for image 2
4. You can get to Vertex 1 from Vertex 4 by going through Vertex 3. This is true for image 1
if ∡PQR = 82°, and the ray QS bisects it, it cuts ∡PQR into two equal halves, ∡PQS and ∡RQS, each of which is then 82/2, or 41°.

The length of each leg is 6
