Construct $△ A B C$ such that $A B = 2.5 c m, B C = 6 c m$ and $A C = 6.5 c m$ . Measure $∠ B$ .

Open in App

Solution

$1.$ Draw $A B = 2.5$ cm
$2.$ Taking $A$ and $B$ as centers, radius $= B C = 6$ cm and $A C = 6.5$ cm,draw two arcs intersecting each other at $C$
$3.$ Join $A C$ and $B C$
Thus, $△ A B C$ is our required triangle.
$∠ B = 90^{\circ}$
