Question

Identify the congruency.

Five Efficient ways to prove triangle congruency.
side-side-side
side-angle-side
angle-angle-side or side-angle-angle
angle-side-angle
hypotenuse-leg
​

Answer 1

1) ASA 2) SAS 3) HL 4) SSS

============

Figure 1

We see two angles and the included side congruency, it is ASA or angle-side-angle.

Figure 2

We see two sides and the included angle congruency, it is SAS or side-angle-side.

Figure 3

We see two right triangles with common hypotenuse and congruent legs, it is HL or hypotenuse-leg.

Figure 4

We see two sides marked as congruent and one side being common, it is SSS or side-side-side.
