Question

Construct a triangle ABC in which ab=ac = 5.2 cm angle A =120 degree

Answer 1

Answer:

steps of construction:

draw a line segment AB = 5.2 cm.at point A , draw an angle of 120 deg.cut an arc of length 5.2 cm., such that angle CAB = 120 deg and CA =5.2 cm.join CB. ...put the tip of the compass at A, and cut an arc . ...put the tip of compass at P and draw an arc.

Answer 2

$\dashrightarrow$ Steps :-

• First, draw a line segment AB of 5.2 cm.
• Next, take a protractor and keep it's mid-point on the point A and draw a ray measuring 120°.
• Then, take a compass and measure it as 5.2 cm using a ruler and keep it's tip on the point A and draw an arc on the ray.
• Now, join the point B to the ray drawn.
• 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.
• Compass :- Compass is used to draw the arc on the ray by taking measurement by scale.
