Es posible hacer un triángulo de 45 45 45 grados ? ? por qué ?

Sí, porque un triángulo equilátero tiene 3 lados congruentes y 3 ángulos congruentes.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

step-by-step explanation:

most likely the answer is a.
