Question

Construct
a triangle PQR in which PQ =
PR = 6cm and QR=7cm.
Draw all its
lines of symmetry​

Answer 1

$\dashrightarrow$ Steps :-

• First, draw a line segment QR of 7 cm.
• Next, take a compass and measure it as 6 cm and keep it's tip on the point Q and draw an arc on the line segment.
• Again, take a compass and measure it as 7 cm and keep it's tip on the point R and draw an arc on the arc drawn before.
• Now, join both the points on line segment to the point where both the arcs meet. Name it as point P.
• Finally, the triangle is constructed.

$\dashrightarrow$ Instruments used :-

• Ruler :- The ruler is used to draw the line segments of accurate measurements and also the drawn lines should be correct and straight always.
• Compass :- The compass is used to draw the arcs above the line segment by taking the measurement as given in the question.
