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.
Solve addition and subtraction problems to find unknown angle measures on a diagram in practical and mathematical problems, (e.g., by using an equation with a symbol for the unknown angle measure).
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.
A right angle measures exactly 90 degrees.
The student will measure right, acute, obtuse, and straight angles.
a number written inside the rays of the angle.
Identify parallel, perpendicular, and intersecting line segments in plane and solid figures. (b)
The shortest distance between two points in a plane, a flat surface, is a line segment.
Identify practical situations that illustrate parallel, intersecting, and perpendicular lines.
