Question

draw a triangle PQR where the angles are in the ratio of 1:2:3. draw a triangle ABC similar to the PQR whose sides are 1/3 times the sides of the PQR.​

Answer 1

Answer:

Step-by-step explanation:

First we need to algebraically calculate the angle of each side of POR.

Let's take x, 2x,3x as the angles.

3x+2x+x=180(angle sum)

x=30

2x=60

3x=90

Now you can use your protractor and construct these angles with random lengths.

Now measure each length and divide it by 3.

Keeping the angles the same, construct using a protractor another triangler similar to POR but 1/3rd in size.
