Ok, well a square is basically two triangles, right? the 45 degree right triangle. if you consider the rules for a 45 degree right triangle, you get: x, x, 2sqrt(x)

plugging in 8, you get the diagonal to be 2sqrt(8) or 4sqrt(2)

Determine whether or not there is a congruence between △abc and △def. if there is such a congruence, then give the reason for it
Andru [333]

There is no congruence between the triangles based on the given information. In general, two sides and an angle not between them are insufficient to specify the triangle completely. In this case, the angles that are congruent are adjacent to non-corresponding sides, so even if SSA correspondence were sufficient to ensure congruence, it would not be sufficient in this case.


The appropriate choice is

... none

2.25X5= 11.25

2 1/4 turns into 2.25 as a decimal, and a pentagon has 5 equal sides, so you take 2.25 and multiply it by 5 to get your answer
