A right(-angled) triangle
120Improved Answer:-It is simply 030 degrees
Every one of the three sides.
A right triangle because it has three sides and three angles. One of the angles though is an 90 degree angle making the other two acute angles because another 90 degree angle or an obtuse angle would not fit. An obtuse triangle also has 2 acute angles.
It will have two 45 degree angles and one 90 degree angle with two of its three sides being equal in length.
There are three sides.

Every one of the three sides.
Such a figure is called a square. Actually only one right angle is enough to force the the other angles to be right, and if three sides are equal, that forces all sides in such a figure to be equal. Exercise: Prove that any 4-sided figure( called a quadrilateral in math books) with three equal sides and one right angle is a square.

All triangles have three sides. Hence "tri" meaning three and "angle" meaning... angle. Three angles. Three sides. All triangles have these.
ALL triangles have three sides and three angles. The three angles always add up to 180 degrees. A right angled triangle has one 90 degree right angle and two smaller angles. No triangle can have any parallel sides. An equilateral triangle has three equal sides and therefore three equal 60 degree angles.
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 will have two 45 degree angles and one 90 degree angle with two of its three sides being equal in length.
If a figure is not a triangle then it does not have three sides ,is the contrapositive of the statement given in the question.
There are three sides.
Angle sum thoerem is when you add all the three sides of a triangle to get a total of 180 degrees. This is what you can use to solve for one missing angle by adding the two angles you have and subtracting them from 180 degree.
