Question

Construct angle ABC in which BC- 4.5cm , angleB- angle C-50°measure AB and AC

Answer 1

★ Answer :-

AB = 3.5 cm

AC = 3.5 cm

$\:$

$\dashrightarrow$ Steps :-

• First, draw a line segment BC of 4.5 cm.
• Next, take a protractor and keep it's mid-point on the point B and draw a ray measuring 50°.
• Again, take a protractor and keep it's mid-point on the point C and draw a ray measuring 50°.
• Join both the rays at one point. If they don't meet, extend both rays. 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 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.
