Answer:
No worries! You can still measure angles without a protractor using some creative methods. Here are a couple of ways:
Using a Ruler and a Calculator
Draw a Right Triangle: Connect the two rays of the angle to form a right triangle. This means drawing a vertical line from one ray to the other.
Measure the Sides: Use a ruler to measure the lengths of the adjacent side (base) and the opposite side (height) of the triangle.
Calculate the Angle: Use the tangent function. The formula is:tan(θ)=adjacentopposite
Then, use a calculator to find the angle:θ=tan−1(adjacentopposite)
Using Paper
Create a Paper Protractor: Fold a piece of paper to create a right angle (90 degrees). Fold it again to create 45 degrees, and keep folding to get smaller angles.
Estimate the Angle: Place the paper on the angle you want to measure and estimate based on the folds.
Understanding Vertical and Adjacent Angles
Vertical Angles: These are the angles opposite each other when two lines cross. They are always equal.
Adjacent Angles: These are angles that share a common side and a common vertex but do not overlap.
