Grade 6 - Shape and Space

Standard 6.SS.1 - Use the fact that the angle sum of triangles is 180º and quadrilaterals is 360º to find the missing interior angle.

Included Skills:

Demonstrate understanding of angles including:
• identifying examples
• classifying angles
• estimating the measure
• determining angle measures in degrees
• drawing angles
• applying angle relationships in triangles and quadrilaterals.
• Observe, and sort by approximate measure, a set of angles relevant to self, family, or community.
• Explore and present how First Nations and Métis peoples, past and present, measure, represent, and use angles in their lifestyles and worldviews.
• Describe and apply strategies for sketching angles including 0°, 22.5°, 30°, 45°, 60°, 90°, 180°, 270°, and 360°.
• Identify referents for angles of 45°, 90°, and 180° and use the referents to approximate the measure of other angles and to classify the angles as acute, obtuse, straight, or reflex.
• Explain the relationship between 0° and 360°.
• Describe how measuring an angle is different from measuring a length.
• Measure angles in different orientations using a protractor.
• Describe and provide examples for different uses of angles, such as the amount of rotation or as the angle of opening between two sides of a polygon.
• Generalize a relationship for the sum of the measures of the angles in any triangle.
• Generalize a relationship for the sum of the measures of the angles in any quadrilateral.
• Provide a visual, concrete, and/or oral informal proof for the sum of the measures of the angles in a quadrilateral being 360° (assuming that the sum of the measures of the angles in a triangle is 180°).
• Solve situational questions involving angles in triangles and quadrilaterals.
