this is a manifold question please help and look at the attachment given below:

show that the following poygonal presentation gives a surface homeomorphic to the connected sum of RP^2 with another copy of RP^2. note that this surrace is the same as the end point of the example above of cut-paste with refleciton. what named surface is homeomorphic to RP^2#PR^2

Show that the following polygonal presentation gives a surface homeomorphic to the connected sum of RP- with another copy of RP . Note that this surface is the same as the end point of the example above of cut-and-paste with reflection. Using this equivalence, what named surface is homeomorphic to RP'#RP?? C C
