Trigonometry is a high school subject that students mostly present difficulties. Due to its
importance to various fields, strategies have been sought to find approaches that could improve
the teaching-learning process of this theme. The main objective of this work is to elaborate a
sequence of activities about Trigonometric ratios using software Geogebra, related with
difficulties of understanding the transition between Triangle Trigonometry and the
Trigonometric Circle. Activities were elaborated in the Geogebra software platform and then
assembled in a dynamic book available in Geogebra official site. Two activities were applied
in a high school class through emergencial remote class model, gathering two classes from the
2nd year of high school from a public school of Santarém-PA. Dialogues that occurred during
the meeting about the activities’ execution were registered and analyzed. It was concluded that
the activities elaborated focusing on the construction of concepts, auxiliated by dynamic
geometry can produce interesting possibilities to the teaching-learning process of this subject.
