What is a scale drawing?

Back

A scale drawing is a representation of an object or space that is proportionally reduced or enlarged to fit on paper, using a specific ratio to represent actual dimensions.

Front

If 1/2 inch represents 5 feet in a scale drawing, how do you find the actual length from the drawing?

Back

To find the actual length, multiply the length in inches by the scale factor. For example, if the length is 3 inches, the actual length is 3 inches x (5 feet / 0.5 inches) = 30 feet.

Front

What is the formula to convert map distance to actual distance using a scale?

Back

Actual Distance = Map Distance x Scale Factor.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

How do you find the measure of the third angle in a triangle?

Back

Subtract the sum of the known angles from 180 degrees. For example, if two angles are 56° and 92°, the third angle is 180° - (56° + 92°) = 32°.

Front

What is a rectangular prism?

Back

A rectangular prism is a three-dimensional shape with six rectangular faces, where opposite faces are equal in area.

Front

What shape results from slicing a rectangular prism vertically from one base to the other?

Back

The resulting shape is a rectangle.

Front

What is a cone?

Back

A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a single point called the apex.

Front

What shape is formed by slicing a cone with a plane perpendicular to its base?

Back

The shape of the cross-section is a triangle.

Front

What is a cross-section?

Back

A cross-section is the shape that results from cutting through an object, revealing its internal structure.
