We use the basic rules of construction to solve the question given. We will use scale and compass to do the construction required.
To construct a ΔDEF, first, we draw a rough sketch with the given measure such that DE = 5cm, DF = 3cm and ∠EDF = 90° for our reference, then follow the steps given below.
∆DEF such that DE = 5 cm, DF = 3 cm and m∠EDF = 90°.
Steps of construction :
Draw a line segment DE of length 5 cm.
At D, draw a ray DX making 90° with DE.
With D as the center, draw an arc of radius 3cm to cut DX at point F.
Join EF to get the required triangle.
Thus, ΔDEF is the required triangle
