I'm deductive reasoning, you start from a __ set of rules and conditions to determine what must be true

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

Show your workcan a right triangle have this sides? *how to prove it without using the pythagorean theorema*

What does the sign of the slope tell you about a line?
