Angles can be either straight, right, acute or obtuse. An angle is a fraction of a circle where the whole circle is 360°. In this game you can learn some angles and what there degree is.
In this game, you will review what you learned about lines and angles. Answer questions correctly to add creatures to your space band. If you answer incorrectly, the aliens will keep the creature for themselves!
Stain Measurement & Calculating Angles of Impact (Screencast)
In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).
A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.
Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.
