Question

Measure ∠ABC given in the adjoining figure and construct an angle DEF equal to ∠ABC.

Answer 1

We can see that $\angle ABC=47°$.
Steps to follow to construct angle $\angle$DEF equal to $\angle$ABC:

• Draw a ray EF with E as the initial point.
• Place the protractor on EF. With its centre at E, mark a point D against the angle 47$°$ of the protractor.
• Join DE. $\angle$DEF = 47$°$ = $\angle$ABC is the required angle.
