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? + b2 = c is true of the side lengths in triangle JKL, then triangle JKL must be a right triangle. I'LL MARK BRAINEST​

the answer will be the last one

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

unless if u could do my questions, if not i wouldn't want to

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
