Question

i need to ger an statements and reasons

Answer 1

 I think you have 2 triangle here that they are similar, and those letters  are vertexes of the triangle.

 

  ABC is the big triangle

 

 

    ADE is inside the the  ABC

 

    D is between AB , and E between AC

 

     DE is parallel with BC

 

    According to 3rd Postulate of Euclid 2 parallel line if intersected with 3 rd line the interior  and Exterior

    angles are Congruent.

 

    therefore:

 

     < B = < D , < C = < E

 

     Therefor ABC & ADE are similar.

 

    AD/ AB = AE / AC   is the proportionality ratio each ratio is the ratio of side opposite to congruent angle.

 

      Note : I don't t think you had any idea about the triangles the you described the problem
