Question

Construct triangle: -Angle E= 46° , Angle F= 75° , DE= 4cm​

Answer 1

$\dashrightarrow$ Steps :-

• First, draw a line segment DE of 4 cm.
• Next, take a protractor and keep it's mid-point on the point E and draw a ray measuring 46°.
• Again, take a protractor and draw an angle measuring 59° from point D, because all the angles together bwcomes 180°. So we can find the angle D.
• Now, the point where bith tye rays meet is caled point F and it measures 75°.
• Finally, the triangle is constructed.

$\dashrightarrow$ Instruments used :-

• Ruler :- Ruler is used to draw the line segments of accurate measurements. The lines should also be straight.
• Protractor :- Protractor is used to draw the ray of accurate degrees or measurements. It is also used to measure the angles.
