Can someone me with this and explain

1. ΔCAT ≅ ΔODG by SSS, Angle D equals 45 degrees

Step-by-step explanation:

Triangles can be proven congruent or the same shape and size by 5 postulates:

To state a triangle is congruent write ΔABC ≅ ΔDEF by and name the pattern. Use the letters for each triangle you see to write or name it.

To identify the pattern, place your pencil on a vertex of the triangle. Trace it and label each congruent part as you come to it as S or A.

For number 1, this would be S - S - S or SSS
