The angle and the hypotenuse are given on a triangle in the first applet.[br][br]Set the second applet to the correct angle.[br][br]Let the hypotenuse = scale factor. Use the enlargement principle to calculate the sides adjacent and opposite.[br][br]Finally, create the triangle with the triangle in the third applet.
