Question

answer the 1st question in step by step

Answer 1

Answer:

Step-by-step explanation:

Given  : ΔABC

to construct : line DE ║to BC

step 1 : draw triangle ABC of any measurment

step 2: draw perpendicular bisector DX of AB* such that DX⊥ADB

step 3:draw perpendicular bisector EY of AC  such that EY⊥ AEC

step 4: join DE

DE ║ BC

to draw perpendicular bisector follow given steps-

   Place the compass at one end of line segment.

   Adjust the compass to slightly longer than half the line segment length

   Draw arcs above and below the line.

   Keeping the same compass width, draw arcs from other end of line.

   Place ruler where the arcs cross, and draw the line segment.
