Question

draw a triangle whose two sides and the included angle are 3 cm 4 cm and 120°​

Answer 1

Answer:

Drawned the triangle whose two sides and the included angle are 3 cm 4 cm and 120°​.

Step-by-step explanation:

To draw the triangle ABC in which the length AB = 3 cm, AC = 4 cm, and the angle , we must follow 4 steps.

The main tools that we are using are a scale, a pencil, and a protractor.

Step 1

    Draw a line AB of length 3cm, by using a scale and write the start and endpoint of the line segment as shown in figure 1.

Step 2

   Draw angle A with a measure of 120 degrees, by using a protractor. For that set the center of the Protractor on point A and count from the right side from and get to . Put a dot in this measurement.

Now using a scale draw a line from point A to this dot. Also, write the angle as . (Figure 2)

Step 3

   Now determine the point C on the line such as AC = 4 cm.

Step 4

    The last step is to draw the line segment BC to get triangle ABC, by using the scale. Draw a line from point B to point C as shown in figure 3.
