Answer:
Answer
Constructing the first triangle:
Step 1: Draw base AB of length 7 cm
Step 2: Place a compass on A and draw an arc of radius 5 cm
Step 3: Place the compass on B and draw an arc of radius 6 cm such that it intersects the arc drawn in step 2.
Step 4: Mark the intersection of the two arcs as C and join A−C and B−C
△ABC is the given triangle.
Let △PAQ be the required triangle.
Step 1: Draw a ray AX from point A on the opposite side of C, making an acute angle with AB.
Step 2: Mark 7 equidistant points A

Step 5: Draw PQ parallel to BC and mark the intersection point on the extension of AC as P.
△PAQ is the required triangle.
