Write short note on the rules on how to bisect a line​

Answer:

First, in your compass take more than half of the given line, i.e, if the line is 5 centimeters, then in the compass take a length more than five centimeters.

Second, Draw an arc, by keeping the compass needle on one end of the line, and do the same by keeping it on the other end.

Two of the arcs will intersect at a point.

Third, do the same, but in the back-ward direction, as in the below of the line. These two will also intersect.

Lastly, draw a line connecting the intersection of the top and below arcs.

I couldnt add the last pic because of the 5 attachments rule. Like I said in the last rule, just join the two arc intersections.

Thank You

Hope u understood

Answer:

here the answer is

If u want nore help please follow

Step-by-step explanation:

STEP 1: Draw a straight line with a ruler. STEP 2: Put the pin of a compass at the end of the line you want to bisect. Set the compass to more than half the length of the line, and draw an arc crossing the line. STEP 3: Keep the width of the compass the same, and from the opposite end of the line draw another arc.

In the figure below mPUR =77 and mST=74 Find mPR
eduard

Answer:

a)

<u>The angle formed by intersecting chords is half of the sum of the intercepted arcs:</u>

  • 1/2(mST + mPR) = m∠PUR
  • 1.2(74° + mPR) = 77°
  • 74° + mPR = 2*77°
  • mPR = 154° - 74°
  • mPR = 80°

b)

<u>The angle formed by two tangents is the half of the difference of the intercepted arcs:</u>

  • m∠PSR = 1/2(mPTR - mPR)
  • m∠PSR = 1/2(247° - (360° - 247°))
  • m∠PSR = 247° - 180°
  • m∠PSR = 67°
