< the point where the two rays meet is called a vertex.
As long as the sides correspond then yes. The other three are: Side-Side-Side Side-Angle-Side - the angle *MUST* be between the two sides Right angle-Hypotenuse-Side
To solve for the cosine (COS) of an angle, you can use the unit circle, where the cosine of an angle corresponds to the x-coordinate of the point on the circle at that angle. Alternatively, you can use trigonometric identities or the cosine function on a scientific calculator by inputting the angle in degrees or radians. For specific problem solving, using the cosine rule in triangles may also be applicable to find unknown sides or angles.
A right angle triangle has an hypotenuse which is its longest side, an adjacent side and an opposite side.
an equilateral triangle has 3 congruent sides and angle measures.
The Sine ratio is Sine(angle) = opposite side / hypotenuse side. This is written in 'short-hand' as Sin(angle) = o / h Similarly the cosine ratio is Cosine(angle) = adjacent side / hypotenuse side. Cos(angle) = a/h Similarly the tangent ratio is Tangent(angle) = opposite side /adjacent side. Tan(angle) = o/a NB THe sides refer to the sides of a right-angled triangle. NNB The angle referred to is NOT the right angle, but a selected angle from the other two angles.
The common end point of the sides (or arms) of an angle is the vertex of the angle.
The common end point of the sides of an angle is called the vertex. The sides are referred to as rays.
< the point where the two rays meet is called a vertex.

The rays are called sides and the common endpoint is called vertex.
