Question

which shape shows exactly 3 angles?

Explanation:

Step1: Recall angle definition

An angle is formed by two - ray or line - segment meeting at a vertex.

Step2: Analyze each shape

Check the number of vertex points where two straight - line segments meet in each shape.

Step3: Count angles

Only a shape with 3 vertex points where two straight - line segments meet will have 3 angles.

Answer:

The shape that has exactly 3 points where two straight - line segments meet shows exactly 3 angles. (Since the actual shapes are not named, we can't point to a specific one among the given ones, but the key is to find the shape with 3 vertex - points formed by straight - line segments).
