Shape Showdown

Explore key geometric concepts including obtuse and acute angles, rectangles, triangles, and polygons. An obtuse angle measures more than 90 degrees but less than 180 degrees, while acute angles measure more than 0 degrees and less than 90 degrees. Familiarize yourself with quadrilaterals, especially rectangles and rhombuses, as well as various polygon types, such as concave and octagonal shapes. Engage with practical applications of geometry through everyday objects like kitchen counters, barbeque grills, and more!
