Front

How many triangles can be formed with given angle and two sides?

Back

Depending on the values of the angle and the two sides, there can be 0, 1, 2, or infinitely many triangles.

Front

What does it mean if no triangle can be formed?

Back

If no triangle can be formed, it means that the given sides and angle do not satisfy the triangle inequality or the conditions of the Law of Sines.

Front

What is the significance of the ambiguous case in the Law of Sines?

Back

The ambiguous case occurs when two sides and a non-included angle are known, leading to the possibility of two different triangles.

Front

What is the relationship between the sides and angles in a triangle?

Back

In a triangle, larger angles are opposite longer sides, and smaller angles are opposite shorter sides.

Front

How do you determine if two triangles are congruent?

Back

Two triangles are congruent if their corresponding sides and angles are equal, which can be tested using criteria like SSS, SAS, ASA, AAS, or HL.

What is the sine of an angle in a right triangle?

Back

In a right triangle, the sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse.
