It depends on you thinking ability
True. An obtuse angle is between 90 and 180 degrees.
The side opposite the 30° angle is shortest, the side opposite the 60° angle is in the middle (length wíse) and the hypotenuse is the longest. The shortest side is half the length of the hypotenuse.
To the nearest ten, 1240, 1050 and 980 respectively.
Yes, it is true that angle 60 degrees has two edges in the angle parts.
Technically, false, because an included angle does not depend on the length of the sides except in right triangles, where the sides will have the same relationship for either of the two acute angles.
Yes... opposite an angle of a right triangle to the length of the triangle's hypotenuse.
False because sine ratio = opposite/hypotenuse
True. In any triangle, the longest side is always opposite the largest angle; the shortest side is always opposite the shortest angle; and the middle length side is always opposite the middle size angle. In an isosceles triangle, there is no middle length side; and the two sides of equal length are opposite the angles of equal size. In an equilateral triangle, all sides are the same length, as are all the angles.
All sides are equal in length and each inside angle is equal to 60 degrees.

It has to be 90 degrees to be a right angle.
