A square is a quadrilateral with four congruent (equal length) sides and four right angles.
A circle is the set of points in a plane that are the same distance from a point called the center.
Recognize that rectangles and squares have special types of angles called right angles. (a)
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 right angle measures exactly 90 degrees.
The edge is the line segment where two faces of a solid figure intersect.
A vertex is a point at which two or more lines, line segments, or rays meet to form an angle. In solid figures a vertex is the point at which three or more edges meet.
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).
a number written inside the rays of the angle.
three letters in order: a point on one ray, the vertex, and a point on the other ray;
