HP Prime Geometry App Tutorial Part 8: Rotating Triangles

HP Prime Geometry App Tutorial Part 8:  Rotating Triangles

Today’s lesson will show how to rotate a triangle given an angle.  The angle is in a counter-clockwise direction. 

For the purpose of this lesson, we will set the HP Prime in Degrees mode.

Draw the Triangle

1.  Set the calculator to Degrees mode.  Draw a triangle with vertices (4,4), (4, -4), and (8, 0). 

Rotate the Triangle

2.  Press (Cmds), 7 for Transformation, 3 for Rotation. 
3.  Select the reference point.  In our example, let’s make this point (0,0) and press [ Enter ].
4.  You are asked for an angle.  Enter 90 for 90°.  Press [ Enter ].

More Rotation

5.  Repeat steps 2 through 4, for angles of 180 and 270.

Thank you.  Until next time, have a great day!
