Bien realizada, pretende ofrecer una comprobación numérica y visual, no una demostración. Tal vez se podría mejorar manteniendo una visualización de los ángulos (en sus respectivos colores) dentro del triángulo.

Comments:
The content is mathematically sound and usable in the classroom
The mathematics are valid
The content is conform to the curriculum for that level
The content is related to the objectives
Comments:
Translation of the mathematical activity into interactive geometry is coherent
The math and the figures are related
The figure is behaving consistently within the activity
The figure shows no ill effect
The numerical values (angles, lengths) are consistent
Functionalities and specific behaviors like sliders, keyboard interaction or macros are well described
Comments:
In this resource, Interactive Geometry adds value to the learning experience
I can produce drawings which are clear and sharp
Different configurations are easily produced
Helps the user to explore, experiment and conjecture
Conjectures can be visually validated
Different representations can be compared
Leads to understand geometric relations rather than numerical values
The activity can not be transposed to paper and pen
Interactive geometry helps reaching the pedagogical goal
Dragging around, you can illustrate, identify or conjecture invariant properties
Dragging around, you infer dependency relations among objects
Comments:
This activity helps me teach mathematics
The students (will) get readily to the point
Hints are given on ways to make the students start
Students initiatives are fostered
Some reports and students snapshots help me foresee the situations that arise
I am helped in identifying resolution strategies, whether correct or invalid, that the students may choose
The feedbacks from the software are discussed and actions to use them are proposed
The feedbacks help the students reach understanding
Remedial actions with respect to expected dead-ends are described
Actions to help the students change strategies are proposed
Advice to determine how and when to synthesize findings is given
How, when and who validates the conclusions are described
The overall activity and what takes place, what are the expected benefits and other possibilities are described
Comments:
I know how to set my class for this activity
The possible configurations (one computer per student or beamer or personal work) are described
Different roles and phases are described
QF.qtx_implementation_exchange
A schedule of the activity is proposed
Comments:
I found easily a way to use this activity in my curriculum progression
The activity benefits later in the classroom
The activity relates easily with my usual teaching
It helps to understand the mathematical notions at work
The experiments they made provide an introduction to the next topic
Comments:
The resource is user friendly and adaptable
The amount of information is satisfactory
The information is clearly presented
