If two angles and the side opposite one of them in one triangle are equal to one side and two similarly located angles in a second triangle then the two triangles are congruent. (The triangles are exactly the same shape and size as each other).

1. It has 3 sides. 2. It has 3 angles. 3. One is side a. 4. The angle opposite side a is Angle A. 5. The sceond side is side b. 6. The angle opposite side b is angle B. 7. The third side is side c. 8. The angle opposite side c is angle C. 9. All sides have equal lenght. 10. All angles have equal measures. 11. Each angle is 60 degrees. 12. The bisector of angle A will bisect side a. 13. The bisector of angle B will bisect side b. 14. The bisector of angle C will bisect side c. 15. Each bisector is perpendicular to the opposite side. 16. Each bisector creates a 30, 60, 90 right triangle.
you cannot determine the sides of a triangle by the angle measures alone because any triangle with different side lengths can have these angle measurements. However if you do know the length of any one of the sides, you can calculate the lengths of the other two sides.The shortest side is the one opposite the 30 degree angle.The hypotenuse (opposite the 90 degree angle) is always twice the length of the shortest side opposite the 30 degree angle.The side opposite the 60 degree angle is always the length of the side opposite the 30 degree angle times the square root of three (about 1.73205).
It is opposite the right angle and it is the longest side.
There are three sides, hypotenuse, opposite and adjacent. But the adjacent and opposite are not fixed sides: it depends on which of the two acute angles you are examining.For either of the non-right angles, the adjacent side is the one which forms the angle, along with the hypotenuse. For the given angle θ, the length of the adjacent side compared to the hypotenuse (adjacent/hypotenuse) is the cosine (cos θ).
An angle cannot be formed by only one ray. However, an angle formed by two opposite rays is called a straight angle.
