Look at the figure. How can you prove the triangles are congruent? It is not possible to determine if the triangles are congruent.

∆ABD ≅ ∆CBD by the SAS Postulate.

∆ABD ≅ ∆CBD by the SSS Postulate.

You can prove them to be congruent.

Step-by-step explanation:

You would use the SSS Postulate. This means Side Side Side.in the figure shown you can see sides AB and BC have one line crossing them making them equal. Same with side AD and CD. With side BD they are congruent because they are equal in size and share both triangles.

Hope this helps.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
