Answer:
60°
Explanation:
When a triangle is graphed using the method that is shown in the picture we know that it is an equilateral triangle. All triangles angles add up to 180° and in an equilateral triangle all sides and angles are congruent.
Using this knowledge we can infer that the angle measure will be 60°.
Proof:
60° + 60° + 60° = 180°
All angles have the same measure because it is an equilateral triangle.
Angles add up to 180°.
