Let’s go through each question one by one.

Question 1:
We are given two triangles: △DEF and △IGH (or similar labeling — we care about markings).
Looking at the tick marks:
- In first triangle: DE has 2 ticks, EF has 1 tick, DF has 3 ticks.
- In second triangle: IG has 2 ticks, GH has 1 tick, IH has 3 ticks.
So all three sides of one triangle match the three sides of the other triangle in length (same number of ticks = same length).
That means
SSS (Side-Side-Side) congruence applies.
✔ Answer for Q1:
D. SSS

Question 2:
Triangles ABC and XYZ.
Markings:
- AB has 2 ticks, BC has 1 tick, angle B is marked with an arc.
- XY has 2 ticks, YZ has 1 tick,
