|---|---|---|---|---|---|
| How do you find the perimeter of a two-dimensional shape? | Add up all of the sides. Perimeter is the distance AROUND the outside of a figure. Measured in units.
🗑
|
||||
| How do you find the area of a two-dimensional figure? | Count the number of square units on the inside of the figure. If the figure is a SQUARE or RECTANGLE you can multiply the length and the width. Measured in square units.
🗑
|
||||
| How do you find the volume of a three-dimensional object? | Volume is the number of CUBIC UNITS on the inside of a 3-d shape. If it is a CUBE or RECTANGULAR PRISM you can multiply the length X width X height. Measured in cubic units
🗑
|
||||
| What is volume? | How many cubic units it takes to fill a 3-dimensional object.
🗑
|
||||
| What is area? | The space covering a 2-dimensional object. The number of square units on the inside of a 2-d shape.
🗑
|
||||
| What is perimeter? | The distance around the outside of a 2-dimensional shape. The number of units when you add up all the sides.
🗑
|
||||
| Triangle with no equal sides. All sides are different lengths. | Scalene
🗑
|
||||
| Triangle with all equal sides. All sides are the same length and all angles are the same. | Equilateral
🗑
|
||||
| Triangle with two equal sides. | Isosceles
🗑
|
||||
| Triangle with all acute angles. | Acute
🗑
|
||||
| Triangle with one right angle. | Right
🗑
|
||||
| Triangle with one obtuse angle. | Obtuse
🗑
|
||||
| An angle less than 90 degrees | acute
🗑
|
||||
| An angle greater than 90 degrees | obtuse
🗑
|
||||
| A angle exactly 90 degrees | right
🗑
|
||||
| a line that goes on forever on both sides | line
🗑
|
||||
| a line that has one endpoint and goes on forever in one direction | ray
🗑
|
||||
| a line that has two endpoints | line segment
🗑
|
||||
| What is a polygon? | A closed figure with straight sides.
🗑
|
||||
| What is the difference between a pyramid and a prism? | Pyramids come to a point. They have no parallel faces. Prisms have a congruent top and bottom (bases) they have parallel faces.
🗑
|
||||
| Name three solid figures. (3-dimensional shapes) | cube, rectangular prism, pyramid, cone, cylinder
🗑
|
||||
| What is the face of a 3-d object? | Flat side
🗑
|
||||
| What is the edge of a 3-d object? | Where two faces meet
🗑
|
||||
| What is a vertex (what are vertices)? | Corners, where two lines meet or two edges meet in a 3-d object.
🗑
|
||||
| Is a circle a polygon? Why or why not? | No-it has curves.
🗑
|
||||
| A 4 sided polygon | quadrilateral
🗑
|
||||
| a 3 sided polygon | triangle
🗑
|
||||
| a 6 sided polygon | hexagon
🗑
|
||||
| an 8 sided polygon | octagon
🗑
|
||||
| a 5 sided polygon | pentagon
🗑
|
||||
| What are parallel lines? | Lines that will never meet, touch or get closer together.
🗑
|
||||
| What are perpendicular lines? | Lines that meet or cross to form right angles.
🗑
|
||||
| What is a two dimensional object? | A flat shape with a length and a width.
