Question

Construct each of the following and give justification :
A triangle PQR given that QR = 3cm,∠ PQR = 15degree
∘
and QP - PR = 2cm.​

Answer 1

Answer:

I just know did the same sum but it has 45° angle. Here it is:

Steps of construction :  

1. Draw a ray OX and cut off a line segment QR = 3cm.

2. At Q, construction ∠ YQR = 45°  with the help of protractor .  

3. On QY , cut off QS = 2cm.  

4. Join RS.  

5. Draw perpendicular bisector of RS to meet QY at P.

6. Join PR. Then PQR is the required triangle.
