To find the right angle without a protractor, use a simple folded paper method. Fold a piece of paper so that one corner meets the opposite edge, creating a triangle. The folded crease will form a perfect 45-degree angle. For a 90-degree angle, combine two 45-degree triangles. This method is effective for quick measurements and ensures accuracy for basic angle needs.
