Question

Which of the following data is not sufficient to draw a unique triangle?

• A. Side, Side, Angle(not included)
• B. Side, Angle(included), Side
• C. Angle, Angle, Angle
• D. Angle, Angle, Side(not included)

Answer 1

Answer: (A), (C)

The correct options are
A

Side, Side, Angle(not included)

C

Angle, Angle, Angle

When all the angles of a triangle are given, then you won't be able to draw a unique triangle. To get a unique triangle at least one side of a triangle should be given.

When two side and included angle is given then, then any unique triangle can be drawn.

Similarily in case of two angles and an included side, a unique triangle can be drawn.
