Muscle fibers contain numerous tubular myofibrils. Myofibrils are composed of repeating sections of sarcomeres, which appear under the microscope as alternating dark and light bands. Sarcomeres are composed of long, fibrous proteins as filaments that slide past each other when a muscle contracts or relaxes.

Answer 2

Answer:

Let Y – Q – Z and Y – P – X. ∆XYZ ~ ∆PYQ …[Given]

∴ ∠XYZ ≅ ∠PYQ …[Corresponding angles of similar triangles]

XY/PY = YZ/YQ = XZ/PQ ...(i) [Corresponding sides of similar triangle ]

But, YZ/YQ = 6/5, ...(ii) [Given]

∴ YZ/PY = YZ/YQ = XZ/PQ = 6/5 ...[Form (i) and (ii)]

∴ sides of ∆XYZ are longer than corresponding sides of ∆PYQ.

∴ If seg YQ is divided into 5 equal parts, then seg YZ will be 6 times each part of seg YQ.

So, if we construct ∆PYQ, point Z will be on side YQ, at a distance equal to 6 parts from Y.

Now, point X is the point of intersection of ray YP and a line through Z, parallel to PQ.

∆XYZ is the required triangle similar to ∆PYQ.

Step-by-step explanation:

i. Draw ∆ PYQ of given measure. Draw ray YT making an acute angle with side YQ.

ii. Taking convenient distance on compass, mark 6 points Y1 , Y2 , Y3 , Y4 , Y5 and Y6 such that YY1 = Y1 Y2 = Y2 Y3 = Y3 Y4 = Y4 Y5 = Y5 Y6 .

iii. Join Y5 Q. Draw line parallel to Y6 Q through Y to intersects ray YQ at Z.

iv. Draw a line parallel to side PQ through Z. Name the point of intersection of this line and ray YP as X.

∆XYZ is the required triangle similar to ∆PYQ.
