Differentiate Shapes Based on Lines and Angles Math Games
In this series of games, your students will learn to classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. The Differentiate Shapes Based on Lines and Angles learning objective — based on CCSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. This learning objective directly references 4.G.A.2 as written in the common core national math standards.

Types of angles are right (exactly 90), acute = less than 90, and obtuse = greater than 90. Lines are parallel if they lie in the same plane, and are the same distance apart over their entire length. Parallel lines never intersect. They are named using two points along each line with the parallel line notation. A line is perpendicular to another if it meets or crosses it at right angles (90°). They are named by using the names of the two lines with the perpendicular notation.
Equilateral triangles have 3 congruent sides and 3 congruent angles. Isosceles triangles have 2 congruent sides that are opposite of each other. The angles formed by the isosceles sides with the 3rd side are also congruent. Scalene triangles have no congruent sides or angles. Acute triangles have 3 angles that are each less than 90. Right triangles have one angle that is exactly 90. Obtuse triangles have one angle that is greater than 90. Classify triangles by side and by angle using the above terms. Classify parallelograms, rectangles, squares, trapezoids, rhombuses using parallel and perpendicular lines.
