3. Creating interactive sketches using Geogebra - 1
Question:

In this assignment, you will need to submit two Geogebra files

    Using sliders construct a triangle with three given sides
    Using sliders construct a triangle with two sides and an included angle

Make sure to label the triangles, mark the vertices and angles.  Display the measurements of angles, sides, area and perimeter.

Use the textbox to verify the following:

    Sum of angles is 180 degrees
    Sum of two sides > third side

Optionally, you can do the following:

    Calculate the area using the formula (1/2) x base x height (For calculating the area, you need to draw the altitude to any one base and use the input bar feature to define a new variable and calculate it as a product of base and height, divided by 2). Display the calculated area as well.

 You can submit the assignment, after zipping the two files.
