Answer 1

Answer:

Sure. Draw a straight line, and with a pair of compasses mark off the longest side. This will be the first side of your triangle.

Set the compasses to the length of the second side. Put the point on one end of the first side you have marked out and draw a circle. A part circle will be enough.

Set the compasses to the length of the third side, put the point on the other end of the first side and draw an arc to intersect the first circle. There are 2 possible points of intersection, one above and one below your initial line.

Draw the triangle(s) using the initial base line and the point(s) you found with the compasses.
