Yes, vertical angles do have the same measures.
They are equal (or 'congruent') angles.
Two or more angles that have the same measure are called congruent angles.
because , since each angle measures the same then all of th angles are the same size :p
It is an equilateral triangle that has 3 equal interior angles of 60 degrees
An enlargement changes the sides but keeps the same angles
They are equal angles.
Angles are considered parallel when their angle measures are the same. These angles are parallel because they are both 180*.
There need not be any relationship at all.
Trigonometric ratios are characteristics of angles, not of lengths. And, by definition, the corresponding angles an similar triangles have the same measures.
No, I learned that in 6th grade
The equilateral triangle.
