A vertex is the point at which two or more lines, line segments, or rays meet to form an angle. The term vertices is the plural form of vertex.
Identify parallel, perpendicular, and intersecting line segments in plane and solid figures. (b)
Recognize angle measure as additive. When an angle is decomposed into nonoverlapping parts, the angle measure of the whole is the sum of the angle measures of the parts.
Recognize that rectangles and squares have special types of angles called right angles. (a)
Understand how to measure acute, right, obtuse, and straight angles.
A right angle measures exactly 90 degrees.
Measure right, acute, obtuse, and straight angles, using appropriate tools, and identify their measures in degrees.
The student will measure right, acute, obtuse, and straight angles.
An angle is formed by two rays with a common endpoint called the vertex. Angles are found wherever lines and/or line segments intersect.
Intersecting lines have one point in common.
