E. ΔDMR & F. ΔMRD are valid names of the triangle.

Which are the valid names of the triangle ?

We know that, a triangle has 3 vertices.

Name of a triangle is always with the name of the vertices together in a clock or anticlockwise manner.

Example : If vertices of a triangle are A, B & C, then name of the triangle are like ΔABC, ΔBCA, ΔCAB, ΔBAC, ΔACB, ΔCBA.

Here, in the given diagram, vertices of the triangle are D, M, R

So, the names ΔDMR & ΔMRD are correct in all the options, others are not names of vertices, so they are not taken.
