How do you construct an equilateral triangle with a compass?

Last Updated: 17th April, 2020

Place your compass point on A and measurethedistance to point B. Swing an arc of this size above (or below)thesegment. 2. Without changing the span on the compass,placethe compass point on B and swing the same arc,intersectingwith the first arc.

Moreover, how do you make an equilateral triangle with a compass?

Method 1 Using a Compass

  1. Draw a straight line. Lay your ruler on the paper, then traceapencil along the straight edge.
  2. Span the segment with your compass.
  3. Trace a quarter-circle arc.
  4. Switch the compass around.
  5. Draw a second arc.
  6. Mark the point where the two arcs cross.
  7. Finish the triangle.

Additionally, how do you construct an inscribed triangle? Bisect another angle. Where they cross isthecenter of the inscribed circle, called theincenter.Construct a perpendicular from the center point toone sideof the triangle. Place compass on the center point,adjustits length to where the perpendicular crosses thetriangle,and draw your inscribedcircle!

Also to know, how do you construct an equilateral triangle without a compass?

Rotate the ruler until the mark representing thelengthof the base line touches the perpendicular bisector. If itcannottouch, extend the bisector. Draw the line, then repeatthisprocess to draw the third line. You now haveatriangle with three congruent sides and threecongruentangles, or an equilateral triangle.

Can you put copies of an equilateral triangle together to form a straight angle?

An equilateral triangle can not be arighttriangle. In a right triangle, however, the 3anglescan NOT be congruent. This is because in arighttriangle, one angle equals 90 degrees.Therefore, youcan't have 3 angles equal 90degrees.
