The two sides (or angles) are said to be congruent.
It is impossible. You need another measurement, such as angle, side length or area etc.

Well they might be but in all cases no. Acute angles just have to have an angle less than 90 degrees to be acute!
Yes, if the angles are the same the two figues are similar. The side lengths don't have to be the same.

the side of an angle measurement
The side that the measurement of an angle starts from.
Of what?
To measure an angle on a wall accurately, use a protractor. Place the protractor on the corner of the angle and align the baseline with one side of the angle. Read the measurement where the other side of the angle intersects the protractor. This will give you the accurate measurement of the angle.

The 3rd side of the right angle triangle can be found by using Pythagoras' theorem.
Yes, if the angles are the same the two figues are similar. The side lengths don't have to be the same.
In that triangle, one of the angles must be a right angle, and another one of the angles must be marked with or the measurement of the angle. Tangent is the ratio of opposite side over adjacent side. The opposite and adjacent sides are determined by the position of the marked angle.
An exterior angle of a triangle is defined to be the angle between one side of a triangle and the extension of an adjacent side. The measurement of this exterior angle is equal to the sum of the two opposite interior angles. See the related links for diagrams and sample problems.
