What do you need to do to change the alignment of selected objects to the left side?

To change the alignment of selected objects to the left side, utilizing the Align menu in the Format Ribbon Tab is the most effective method. The Format Ribbon provides a comprehensive set of alignment tools specifically designed for objects within your presentation, including shapes, texts, images, and other elements. When you access the Align menu, you are presented with various options that allow you to align the objects precisely in relation to one another or to the slide itself.

Choosing this method streamlines the process of alignment, as it keeps the relevant options in one dedicated area for ease of access. Additionally, this option allows for relative alignments that can help in creating a professional-looking slide by ensuring that multiple objects are aligned correctly, enhancing overall visual consistency.

Other methods may not offer the same breadth of functionality. For instance, right-clicking to select "Align left" is a valid shortcut but may not present all alignment options available in the Format Ribbon. Centering options from the Home Tab pertains more to text alignment rather than object alignment, which does not apply in this scenario. Furthermore, the Arrange options found in the View Tab focus more on layering and ordering elements rather than aligning them.

Therefore, using the Align menu in the Format Ribbon Tab is the most straightforward and effective approach
