Standards with the same topic and subject but for other grades
The student will measure right, acute, obtuse, and straight angles.
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.
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.
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.
A right triangle has one right angle.
Recognize that rectangles and squares have special types of angles called right angles. (a)
