• AB = 4 cm, BC = 8 cm and CA = 2 cm

• BC = 5.2 cm, ∠B = 90° and ∠C = 110°

• XY = 5 cm, ∠X = 45° and ∠Y = 60°

• An isosceles triangle with the length of each equal side 6.2 cm

Answer 1

XY = 5 cm, ∠X = 45° and ∠Y = 60°

Explanation:

Let us draw the triangle according to measurements given in respective options.

For (a) As we can see, triangle cannot be drawn.

For (b) Triangle cannot be formed.
