How can I select tools and techniques to analyze the relationship among the sides of a right triangle

If it is a special triangle (either 45-45-90 or 30-60-90) then you select the tools from the rules of special triangles.

Otherwise, if you know two angles and a side of the triangle (AAS or ASA) you use law of sines. If you know two sides and an angle (SSA) you can also use law of sines.

Use the law of cosines when you know two sides and the angle in between them (SAS).

Could ΔABC be congruent to ΔADC by SSS? Explain.

Vera_Pavlovna [14]

There are 5 ways to test if two figures are congruent, namely;
side-angle-side(SAS)
Angle-side-angle (ASA)
Angle-angle-side(AAS)
Hypotenuse-leg (HL)
3 Sides (SSS)
here we shall focus on SSS. When the three corresponding sides of 2 figures say a triangle have the same length we will conclude that the triangles are congruent by SSS.
Therefore from our choices we can conclude that triangles ABC and ADC are only congruent if the two other side have the same length and BC=DC.

The answer is yes;
B] Yes, but only if BC=DC
