Question

In the diagram below, DF = JL = a FE = LK=b and triangle DEF is a right triangle.

Use the drop-down menus to complete the proof that if the equation a? 62
is true of
the side lengths in triangle JKL, then triangle JKI must be a right triangle.

Angle L,

a^2+b^2=DE^2

De^2=c^2 and CE=c

angle L=F
