A pair of congruent triangles will have the same three side lengths and the same the angles. The equal sides and angles may not be in the same position due to turning or flipping, but they are always there. You can draw a phone with congruent lines on each triangle.

Like terms are terms with the exact same variables, and the exact same degree of each variable...simply put, the exponents of each variable have to be exactly the same.
The given term 12 ad³ has variables a and d. a has a degree of 1 and d has a degree of 3.
The term 3ad³ has the same variables and the same degree, and is therefore the like term.
