Identify the sides of a right triangle using trigonometry and find unknown angle measures.

This slide deck will walk students through a brief recap of the trigonometric ratios and how to use the inverse. Then they will use their knowledge of the trig ratios and inverses to solve for unknown angle measures in a right triangle. There are also challenge questions that will stretch their thinking.

Slides are ready for students to type in their work and final answers. They work great with Schoology & Google Classroom to assign individual student copies. These slides are easily printable if digital resources are not available. Slides are editable if you would like to change the given diagrams or add more practice.

Worked out answer keys are provided for all slides.

Teacher Tip: Duplicate the slide deck to separate the activity from the answer key. These slides also work great if turned into a PearDeck. In my classroom I use the draw feature in PearDeck with plug & play graphics tablets.
