Question

in triangle pqr a and B are respectively the midpoints of sides PQ and QR if equals to 60 degree then pqr is equals to how much degrees​

Answer 1

Answer:

180 degrees

Step-by-step explanation:

cause its the total angle of a triangle

Answer 2

Answer:

Angle PQR is 120°.

Step-by-step explanation:

According to the question,
Angle A + Angle B = 60°
We know that sum or total angle of a triangle is 180°.
When we join mid points A and B, it forms a ∆AQB.
According to triangle properties,
Angle AQB = Angle PQR
Angle A= Angle P ( Corresponding angles)
Angle B= Angle R ( Corresponding angles)
Now , In ∆AQB,

angle QAB + angle QBA + x =180° (Let angle AQB be x)
60° + x = 180°
=>x = 120°
     So angle AQB =120°
=>Angle PQR = 120°.
