The given statement in the image is:

$\alpha = 90^\circ - \beta$

This is a right triangle, where we know that the sum of the angles in any triangle is always 180°. In a right triangle, one angle is 90°, and the other two angles (α and β) must sum to 90°. Therefore, the equation $\alpha + \beta = 90^\circ$ holds true, which can be rewritten as:

$\alpha = 90^\circ - \beta$

This confirms the statement is True.

Let me know if you'd like more details or if you have any questions!

Here are some related questions:

1. How do we know that the sum of the angles in any triangle is 180°?
2. Can you apply this rule to other types of triangles as well?
3. How would you find the third angle in a triangle if you know two angles?
4. What is the relationship between the sides of a right triangle and the angles?
5. Can this rule ($\alpha = 90^\circ - \beta$) be applied to any right triangle?

Tip: In right triangles, you can use trigonometric ratios (sine, cosine, tangent) to find unknown angles and sides.
