Understanding the Ambiguous Case in Triangles

What is referred to as the 'ambiguous case' in triangle geometry?

• A case where three or more triangles can be formed.

• A scenario where only one unique triangle can be formed.

• A case where no triangle can be formed.

• A situation where two different triangles can be formed with the same given information.

How do you confirm the existence of a triangle before solving for the ambiguous case?

• By checking if the given side is longer than the height.

• By comparing the side lengths.

• By using the Pythagorean theorem.

• By ensuring the sum of angles is 180 degrees.

What indicates that there might be a second triangle in the ambiguous case?

• The sum of the two angles found is less than 180 degrees.

• The sum of the two angles found is exactly 180 degrees.

• The sum of the two angles found is more than 180 degrees.

• The two angles found are equal.

What role does the sine law play in solving ambiguous case problems?

• It helps in finding the possible angles given side lengths.

• It is used to calculate the area of the triangle.

• It is used to determine the height of the triangle.

• It confirms the type of triangle (acute, obtuse, or right).

How can you verify that a triangle meets the conditions for the ambiguous case?

• By ensuring one side is longer than the other.

• By confirming the given angle is acute.

• By checking if the opposite side is longer than the adjacent side.

• Both A and B are correct.

What is the significance of calculating the height 'H' in ambiguous case problems?

• To determine the area of the triangle.

• To confirm the triangle's existence by comparing it with the given sides.

• To calculate the perimeter of the triangle.

In the ambiguous case, what does finding two different angles for the same set of side lengths and an angle signify?

• That only one triangle is possible.

• That no triangle can be formed.

• That exactly two distinct triangles can be formed.
