Question

To Construct triangle BAT in which BA = 8cm , angle B=50° and angle T=80°, what is
the measure of angle A and which criterion will be used
a) 50°, AAS
b) 50°, ASA
c) 80°, ASA
d) 80°, AAS​

Answer 1

Answer:

Clearly,

∠ABC+∠BCA+∠CAB=180

∘

[By angle sum property of triangle]

⇒∠BCA=180

∘

−∠ABC−∠CAB

⇒∠BCA=180

∘

−100

∘

⇒∠BCA=80

∘

Steps of construction:

1) Draw a line segment BC of length 8 cm.

2) Draw ∠CBX such that ∠CBX=50

∘

.

3) Draw ∠BCY with Y on the same side of BC as X such that ∠BCY=80

∘

.

4) Let CY and BX intersect at A.
