1. Write a two-column proof. Given: Triangle ACD is isosceles; <1 is congruent to <3

Prove: Segment AB || Segment CD

Check it below, please

Step-by-step explanation:

Hi there!

Let's prove segment AB is perpendicular to CD. Attention to the fact that a two column proof has to be concise. So all the comments can't be exhaustive, but as short as possible.

Let's recap: An isosceles triangle is one triangle with at least 2 congruent angles.

Statement                     Reason

                    Given

       Isosceles Triangle the altitude, the bisector coincide.          

              Bisector equally divide a line segment into two congruent      

Right angles, perpendicular lines.                  

                   Perpendicular Line segment      

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

gimmee one of those gold crowns!
