For 1, simply draw an equilateral triangle. The angles should be 60°, 60°, 60°. The sides can be any length, but they should become equal if you just draw out one 60° angle and connect the two edges. For 2, just draw a right triangle with angles of 90° (obviously), and two others that are not 45° each. So, you could draw a 30°, 60°, 90° triangle, for example.
For 6-8, you have to just remember that when you add up the angle measures of a triangle, the total will <em>always</em> be 180°.
So, for 6, the answer is 60°. For 7, the answer is 118°. For 8, the answer is 27°.
