What definition is dynamically being illustrated here? [i][br]Feel free to move the triangle's white vertices anywhere you'd like! [/i]
[b][color=#000000]The COSINE OF AN [color=#1e84cc]ACUTE ANGLE[/color], when defined in the context of a right triangle, is the ratio the [color=#cc0000]leg adjacent[/color] [color=#1e84cc]that angle[/color] to the hypotenuse. [/color][/b][br][br]Note that this applet displays the cosine of the [b][color=#1e84cc]blue angle [/color][/b]as a percentage.
