Answer:
Step-by-step explanation: Tip 1) Always Start from the More Complex Side.
Example Q1) Prove the identity tan⁴x = sec²x (tan²x-1)+1.
Tip 2) Express everything into Sine and Cosine.
Tip 3) Combine Terms into a Single Fraction.
Tip 4) Use Pythagorean Identities to transform between sin²x and cos²x.
Tip 5) Know when to Apply Double Angle Formula (DAF)
Answer:

What makes DEF and DGF congruent
We have:
--- this is indicated by the single line on both sides
Also:
--- both triangle share same side
For SAS to be true;
2 sides and 1 angle must be equal in either triangles
So far, we have:
---- S
---- S
The additional to complete the proof is:
---- angle between the above sides
The first 4 terms are 2, 2/3, 2/9, and 2/27
