If jk and lm are congruent and parallel, then jkl and mlk are congruent. true false

TRUE

Step-by-step explanation:

Given that line segment JK and LM are parallel. From picture we see that LK is transversal line.

We know that corresponding angles formed by transversal line are congruent.

Hence ∠JKL = ∠ MLK ...(i)

Now consider triangles JKL and MLK

JK = LM  {Given}

∠JKL = ∠ MLK { Using (i) }

KL = KL  {common sides}

Hence by SAS property of congruency of triangles, ΔJKL and ΔMLK are congurent.

Hence given statement is TRUE.

I think the correct answer is undefined terms  In an axiomatic system, points, lines, and planes belong to the category of undefined terms. These systems do not have definite shape and sizes. Lines and planes can extend infinitely.
