    you will need to see side- angle - side in that order

    you are looking for SAS you are given an angle (the bottom angle) and a side (the line down the middle) what else do you need ?

    you want to use side -angle - side check off what you have, and what is left over that you need?

    ignore the letters. Just get the idea you are told about an angle and a side you want to use side- angle - side what do we need (the answer is either: angle or side ) which do we need?

    I'm sorry Phi. I thank you for having patience with me. I just don't have an eye for this stuff.

    yes we need a side now we need to figure out which side

    when we write side-angle-side that means the "parts" are *next to each other" so put your finger on the side we know, then move to the angle we know then move to the next side... that last side is what we need

    and then we do the same thing for the other triangle we want the bottom sides to be equal

    to name a side we list the end points (order does not matter) so a side is named using two letters. the start and the end letter

    FYI, KET is an angle angles use 3 letters, start, pointy end, and then end point

    I'm sorry for taking up your time yet once again. Your effort is greatly appreciated, Sir. :) I really like how you actually explain to me until I get it myself. So thank you.
