Answer» 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 1
,A 2
,A 3
,...,A 7
on ray AX. Step 3: Join A 5
to B. Step 4: Draw A 7
Q parallel to A 5
B and mark the point on the extension of line AB as Q. Step 5: Draw PQ parallel to BC and mark the intersection point on the extension of AC as P. △PAQ is the required triangle. |
