For ΔJNM, the following facts are given:
KL || MN
KL = 8 ft
MN = 10 ft
JL = 3.2 ft
MK = 1.5 ft
Answer the following:
Is ΔJNM ~ ΔJLK? Support your answer with a postulate or theorem.
Find the length of JN. Show all your work.
Find the length of JK. Show all your work.
What is the area ratio of ΔJNM to ΔJLK? Show all your work.
+36916 Is ΔJNM ~ ΔJLK? Support your answer with a postulate or theorem.
Yes S-A - S
Find the length of JN. Show all your work.
kl is to mn as jl is to jn
kl / mn = jl/jn
8/10 = 3.2 / jn use this to find jn then ln = jn - jl = jn - 3.2
Find the length of JK. Show all your work.
kl / mn = jk/ (jk+ mk)
8/10 = jk/ (jk+1.5) solve for jk
Are these right triangles? use what you have found and are given to see if pythagorean theorem is true
if they ARE right triangles then are of a right triangle = 1/2 leg1 * leg2
