        Acute Triangles (English Voice) | Math Active

        Learners explore properties of acute triangles in this voice-narrated interactive activity.  New vocabulary is defined to explain how triangles are categorized by angle measure.  Next, learners use a virtual protractor to measure and sort triangles.  Is the triangle acute or obtuse? The final segment prepares students to learn how triangles are also categorized by side length to form scalene, equilateral, and isosceles figures.
