The image you uploaded shows a set of three triangles where you are asked to measure the angles at vertices \(A\), \(B\), and \(C\), and then complete a table by summing the angles of each triangle.

To solve this:

1. Measure or calculate the three internal angles (\(\angle CAB\), \(\angle CBA\), and \(\angle ACB\)) of each triangle.
2. Add these angles to verify that their sum equals \(180^\circ\) (since the sum of the angles in any triangle must always equal \(180^\circ\)).

Would you like me to walk you through how to calculate or estimate these angles based on specific geometric properties or dimensions of the triangles? Let me know if you want further clarification or a method for determining these values. 

Also, here are five related questions to help expand your understanding:

1. How do you determine the angles in a triangle if only the sides are given?
2. Why do the angles in any triangle always sum to \(180^\circ\)?
3. Can you name different types of triangles based on their angles?
4. How can the Pythagorean theorem help in determining angles in right triangles?
5. How can trigonometric functions (like sine, cosine, and tangent) be used to find unknown angles?

**Tip:** If you know two angles in a triangle, you can always find the third by subtracting their sum from \(180^\circ\).

Mide los ángulos de los siguientes tres triángulos y luego completa la tabla.

Learn how to measure the angles of three different triangles and complete a table by adding their interior angles. This exercise teaches the Triangle Sum Theorem, where the sum of a triangle's interior angles is always 180°. Suitable for students in Grades 5-7.
