Question

Suppose you have a straightedge and a compass. How can you draw a triangke with sides 7,9 and 12 cm?

Complete description of the algorithm used to construct a triangle if the lengths of three sides are AB = 12, AC = 9 and BC = 7 :
With the straightedge, draw line l.
Draw point A anywhere on this line.
Draw point B on line l, at the distance
from point A.
Using a compass, draw a circle with the center in point A and radius
.
Using a compass, draw a circle with the center in point
and radius
please help me

Answer 1

Draw point A anywhere on this line.

Draw point B on line l, at the distance 12

from point A.

Using a compass, draw a circle with the center in point A and radius

9

Using a compass, draw a circle with the center in point B

and radius 7
