Proof

Given the figure in document with 3BF=2FC , AE=2EF and [DEF]=1 a- FIND [DFC] b-FIND AC/AD

Proof

ABCDEF is a convex hexagon with side AB parallel to CF side CD parallel to BE and side EF parallel to AD prove that [ACE]=[BDF] as shown in document (attached).

Proof

Given the figure in document with D=midpoint of AC and E = midpoint of BD a-find BC/BF b-find [AEB] if [BEF]=1

Conic questions...

My class is studing graphs that have geometric interpretations which is known as conic sections. How do I explain how the curves can be created geometrically? Can you tell me if a conic section is considered to be a function?

Proofs

1- prove that the diagonals of arhombus bisect each other at right angels. 2- prove that diagonals of a kite or dart (possibly extende) intersect at right angels. (Note: kite is a convex quadrilateral in which 2 pairs of adjacent sides are congruent dart is a non convex quadrilateral in which 2 pairs of adjacent sides are congruent) Please see the attached file.
