Answer: [tex]B.\ \triangle{DMR}\\\\E.\ \triangle{MRD}[/tex]
Step-by-step explanation:
From the given picture we have given a triangle with vertices as
Vertex M
Vertex D
and Vertex R.
To give a name to a triangle we use the labels of the vertices of the triangle, that generally written in capital letters.
When we start naming a triangle, we start with any vertex but we need to keep the letters in order as we move around the triangle.
Therefore, the possible valid names of the given triangle are :-
[tex]\triangle{MDR}\\\\\triangle{DRM},\\\\\triangle{RMD}\triangle{DMR}\\\\\ \triangle{MRD}\\\\\triangle{RDM}[/tex]
