Welcome, Triangle Explorer! [br]Before we start classifying triangles, let's familiarize ourselves with the tool in front of us. This is your very own [b]interactive triangle[/b]. You can change its shape however you like.[b]Your First Task:[/b][list=1][*]Click and hold one of the corners (the points labeled [b]A[/b], [b]B[/b], or [b]C[/b]).[/*][*]Drag the point anywhere on the screen.[/*][/list][b]What to Watch For:[/b][list][*]As you move the vertices, look at the numbers next to the sides. You'll see their lengths change in real-time![/*][*]Also, notice the measurements inside the angles. They will grow and shrink as you reshape the triangle.[/*][/list]Go ahead and play around! Try to make a very tall, skinny triangle, and then a short, wide one. When you feel comfortable changing its shape, you're ready for the next activity.
