Measure an angle from a photo
Place three points, check your perspective, and save a visual measurement.

Start with a clear, straight-on image
Choose a photo that shows the two sides of the angle clearly. A tilted camera view can distort the apparent angle, so aim for a view perpendicular to the surface.
Align the three measurement points
Place one point at the vertex and one on each side of the angle. Move them carefully so the overlay follows the visible lines rather than a shadow or nearby edge.
Read and check the result
Read the angle in degrees and recheck point placement. For a diagram, use the screen protractor; for a real object, a clear photo can help you place points more consistently.
Save a PNG for your next step
Export the measurement image and save or share it through your device. Keep the source photo if you want to revisit the point placement later.
