How can I join the endpoints of 2 lines without affecting their lengths?

[cljones300]

As seen in the screenshot, I am trying to form a triangle where I know the lengths of each 3 sides. But not the angles. Is there a way I can join the 2 lines that don't meet, and keep their lengths the same?

Thank you

Hi,

the best way to achieve your job is to start drawing circles that represent your triangle sides then draw lines when those circles intersect . start from the horizontal line to draw the other sides .

Would you care to elaborate? Thank you

Draw 1st line w/ known length.

from 1 of its end point draw a circle with 2nd known length

from the other end point draw a circle with 3rd known length.

connect end points of 1st line to the intersection of 2 circles.

As @imadHabash fantastic answer suggests, you (per your inquiry) are given three lengths. You have drawn A to B, B to C, and C to D. You are needing to close that triangle and this can be done with circles.

To close that triangle draw circle G with radius  of length equal to the length of A to B and center it at point B. Draw another circle F with radius equal to the length of C to D and centered at point centered at point C.

Since circles have a constant radius from their center, any point from the center of circle G to its edge will be equal the length AB and any line drawn from the center of circle F will be equal to CD.

The two circle intersect at point E. Therefor if you draw a line from point B to point E it will be equal to the length of line AB. If you draw a line from point C to E it will be equal to the length of line CD
