Question

When you open a stepladder, you use a brace on each side of the ladder to lock the legs in place. Explain why the triangles formed on each side by the legs and the ground (AABC and ADEF in the diagram) are congruent.

​

Answer 1

They are congruent because they have corresponding angles and sides. They are prooven congruent by SAS, AAS, and the SSS theroms/postulates.

I hope this helps, have a nice day! :)
