Question

4. Can we construct a triangle with the following angles?
(a) 30°, 120° and 40°
(b) 45°, 70° and 65°
(d) 90°, 40° and 50°
(e) 120°, 80° and 10°
(c) 1350, 35° and 30°​

Answer 1

Step-by-step explanation:

a. yes

b. yes

d. yes

e. no

c. no

Answer 2

a-no, b-yes ,c-yes ,d- no ,e- no

Step-by-step explanation:

firstly we cannot construct a triangle if the sum of its angles is not equal to 180°. for example in 1 question the sum is=30°+120°+40°=190° so it cannot form a triangle and in 2 question sum of angles =45°+70°+65°=180 so it can form a triangle.
