A right triangle is shown. One side is vertical, one side is horizontal, and one side is diagonal. The right angle is between the vertical and horizontal sides.
HL requires a right angle, so use a protractor to create a right angle.
A right triangle is shown with vertical and horizontal sides.
Choose a leg of the original right triangle. Cut a piece of string the length of that leg.
A right triangle is shown. One side is vertical, one side is horizontal, and one side is diagonal. The right angle is between the vertical and horizontal sides. A line segment of the same length as the vertical side is next to the vertical side.
Lay the string along the corresponding leg of the right angle that you drew in Step 1 and make the leg the same length as the string by either extending the side or erasing part of the side.
A right angle is shown with vertical and horizontal sides. A line segment is next to the vertical side. The vertical side is longer than the line segment and so the top of the vertical side is crossed out to make them the same length.
Cut a piece of string the length of the hypotenuse of the original right triangle.
A right triangle is shown. One side is vertical, one side is horizontal and one side is diagonal. The right angle is between the vertical and horizontal sides. A line segment of the same length as the diagonal side is next to the diagonal side.
Lay one end of the string at the top of the leg that you created in Step 3. Make the other end of the string intersect the other side of the right angle, forming a triangle. Trace the string. Make the bottom leg of the triangle the correct length by either extending the side or erasing part of the side.
