Given the two triangles, you have to determine wich sides and angles are equal.
Normally, the markings over the lines indicate that they are equal.
These lines are called tick marks.
The number of marks indicate which sides are congruent.
So the pair of sides with one tick mark will be equal.→BC=FE
The pair of sides with two tick mars will be equal.→AB=DE
The pair with three tick marks will be equal.→AC=FD
The same happens with the angles, those marked with the same amount of tick marks will have the same measure, so:
Angles marked with one tick mark are equal →∠A=∠D (yellow ones)
Angles marked with 2 tick marks → ∠C=∠F (blue ones)
Angles marked with three tick marks → ∠B=∠E (red ones)
