Question

Draw a triangle PQR in which angle p=120°, PQ= PR= 4.5cm. Measure the other two angles.

Answer 1

here we don't need to measure the angles as this question can be solved by a property...
we know if in a triangle the two sides are equal then the opposite sides are equal as well and that the triangle is isosceles . As in this case the sides are equal therefore the other two angles are equal as well.
hope it helps u friend...

Answer 2

Step-by-step explanation:

<p+<Q+<R=180°

120°+2<Q=60°

<Q=30°

<Q=<R=30°
