What is the general form of the equation of a circle with center at (a, b) and radius of length m? . a. x2 + y2 − 2ax − 2by + (a2 + b2 − m2) = 0 . b. x2 + y2 + 2ax + 2by + (a2 + b2 − m2) = 0. c. x2 + y2 − 2ax − 2by + (a + b − m2) = 0. d. x2 + y2 + 2ax + 2by + a2 + b2 = -m2.

Asequence {an} is defined recursively, with a1 = 1, a2 = 2 and, for n > 2, an = an-1 an-2 . find the term a241

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
