In the given isosceles △RED, RE = RD. If ∠R = 70°, find the measures of ∠E and ∠D. |
|
Answer» r :-∠E measures :- 55°∠D measures :- 55° Steps :-First, draw a line segment RE of 5 cm.Next, take a protractor and keep it's midpoint on the POINT R and draw a ray measuring 70°.Then, take a cómpàss and measure it as 5 cm and keep it's tip on the point R and draw an arc on the ray.Now, joìn the point E to the point where the arc and the ray meets. Name it as point D.Finally, the TRIANGLE is constructed. Instruments used :-Ruler :- The ruler should be used in all the constructions so that it RESULTS in accurate measurements and also the drawn lines should be straight.Cómpàss :- The cómpàss is used to draw the arc by TAKING measurement on the ray.Protractor :- The protractor is used to draw the ray of accurate measurements and also to measure the angles. |
