100
What is Perimeter?
What is the distance around a geometric figure?
100
What is an angle?
Angle that is formed by two rays with a common endpoint. The two rays are the sides of the angle.
100
MCC7.G2
MCC7.G.2. Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.
100
What is an adjacent angle?
An angle next to another: either of the two angles that are formed by the intersection of two straight lines and lie on the same side of one line
100
What is a vertex?
A common endpoint.
200
What is Circumference?
What is the distance around a circle?
200
What is a right angle?
A right angle is an angle that measures exactly 90 degrees.The "ґ" symbol indicates a right angle.
200
MCC7.G.3
MCC7.G.3. Describe the two-dimensional figures that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids.
200
What is a verticle angle?
An angle formed by intersecting lines: either of a pair of equal angles formed on opposite sides of the point at which two lines intersect
200
What are perpendicular lines?
A line meeting another at a right angle, or 90°.
300
What is pi, and what is the most common way of using it?
What is the ratio of circumference (C) to diameter (D). It is most commonly used as 3.14 or 22/7.
300
What is an acute angle?
An acute angle is an angle that measures less than 90 degrees.
300
MCC7.G.4
MCC7.G.4. Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.
300
What is a skew angle?
A skew angle is an acute angle subtented by a line that is normal to the longitude axis of the structure and a line that is parallel to or coinciding with a alignment of its end as applied to oblique bridges.
300
What are parallel lines?
Two lines that never touch, meet, or cross.
400
What is Diameter?
What is the distance on a circle from one point through the middle, to a point on the opposite end of the circle.
400
What is an obtuse angle?
An obtuse angle is an angle that measures more than 90 degress, but less than 180 degrees.
400
MCC7.G.5
Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem; to write and solve simple equations for an unknown angle in a figure.
400
What is a complementary angle?
The sum of two angles that when added together equal exactly 90 degrees.
400
What is a transversal line?
A line intersecting two or more lines.
500
What is radius?
The distance from the center of a circle to a point anywhere on the circle.
500
What is a straight angle?
An angle that measures exactly 180 degrees.
500
MCC7.G.6.
Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
500
What is a supplementary angle?
An angle that is formed by adding two angles and getting exactly 180 degrees.
500
What is volume?
Volume is the measure of the amount of space inside of a solid figure, like a cube, ball, cylinder or pyramid. It's units are always "cubic", that is, the number of little element cubes that fit inside the figure
