WebASA (Angle-Side-Angle): If two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent. The ASA Postulate was contributed by Thales of Miletus (Greek). In most systems of axioms, the three criteria—SAS, SSS and ASA—are established as theorems. WebThe Area of a Triangle using Sine.

Finding the Area of a Triangle with the Law of Sines
WebThere can be two since sin (theta) = sin (180-theta) for all values of theta that are real numbers e.g. -1000.98, sqrt (2) etc. Since you are using the sin^-1 function you will only ever get 1 angle as the range is defined from -90 to 90 degrees (which is -pi/2 to pi/2 in radians). You can it sketch on desmos to see what it look likes. newstead restaurants on the river
