    could you split quadrilateral AEDF into two triangles and find congruent by SAS, since AD = AD using the "reflective property" and find same answer that way?

    I'm fed up with angles. This subject is boring

    He sounds like a giddy child every time he says “Diagram”. It’s just hilarious!

    You saved me again Khan. I follow maths in the Netherlands, but we don't have to give reasons why, which made me very confused of the statements! I knew the statements are true, but why would you do math if you don't understand it?
    Thanks!

    I made an extremely convoluted proof to solve the first problem, but it accidentally also solved the second problem lol. Essentially I made a line segment AD, and showed the triangle CAD and BAD were congruent. Therefore BD is congruent to CD. Using this and the fact that the angles FDC and EDB are congruent that meant the triangles FCD and EBD were congruent. Meaning ED is congruent to FD (Second problem), and if CD is congruent to BD and DF is congruent to DE that means since point D sits on the line between BF and CE that BF and CE are congruent. This stupid proof somehow solves both problems in probably the worst way possible

    can you say it is CPCTC?

      the regents no longer accepts CPCTC as a justification
