Recognize that rectangles and squares have special types of angles called right angles. (a)
A circle is the set of points in a plane that are the same distance from a point called the center.
Compare and contrast plane and solid figures (circles/spheres, squares/cubes, and rectangles/rectangular prisms) according to their characteristics (number and shape of their faces, edges, vertices, and angles).
Use symbolic notation to describe parallel lines and perpendicular lines. (b)
Subdivide a three-sided or four-sided polygon into no more than three parts and name the resulting polygon(s). (c)
Identify parallel sides, congruent sides, and right angles using geometric markings to denote properties of quadrilaterals.
Identify and describe plane figures (circles, squares, and rectangles), according to their characteristics (number of sides, vertices, and angles). Squares and rectangles have four right angles.
Understand that points, lines, line segments, rays, and angles, including endpoints and vertices are fundamental components of noncircular geometric figures.
An angle is formed by two rays that share a common endpoint called the vertex. Angles are found wherever lines or line segments intersect.
A line segment is part of a line. It has two endpoints and includes all the points between and including the endpoints. To name a line segment, name the endpoints (e.g., 𝐴𝐵‾ read as “line segment 𝐴𝐵”).
