Question

Construct triangle ABC with BC =7.5cm AC =5cm and measure angle C =70 degree

Answer 1

$\dashrightarrow$ Steps :-

• First, draw a line segment BC of 7.5 cm.
• Next, take a protractor and keep it's mid-point on the point C and draw a ray measuring 70°.
• Then, take a compass and measure it as 5 cm and draw an arc on the ray drawn.
• Now, join the point B to the point where the ray and arc meets. Name it as point A.
• Finally, the triangle is constructed.

$\dashrightarrow$ Instruments used :-

• Ruler :- The ruler is used to draw the line segments of accurate measurements and also the drawn lines should be correct and straight always.
• Protractor :- The protractor is used to draw the rays of accurate measurements of degrees. It's also used to measure the angles given.
• Compass :- The compass is used to draw the arcs on the ray by taking the correct measurement as given in the question.
