=
Line segment AB is drawn in the plane. Where should point C be placed so that ABC is a right triangle? …so that it is an isosceles triangle? …so that it is obtuse? This activity will allow you to explore these questions.======

=
Place a constraint or condition on the triangle, and manipulate its shape, sides, and angles to change the identifying properties of the triangle. Great for practicing triangle vocabulary, such as scalene, isosceles, obtuse, acute, etc. Also use the side and angle measurement tools to identify more characteristics about the triangle.======
