Unit 7 Angles, Triangles, and Prisms

Front

What is the formula for calculating the surface area of a triangular prism?

Back

Surface Area = (Base Area x 2) + (Perimeter of Base x Height)

Front

What are the conditions for three lengths to form a triangle?

Back

The sum of the lengths of any two sides must be greater than the length of the third side.

Front

What is the sum of the interior angles of a triangle?

Back

180 degrees.

Front

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

Back

Subtract the sum of the known angles from 180 degrees.

Front

What is the formula for calculating the volume of a rectangular prism?

Back

Volume = Length x Width x Height.

Front

What is a prism?

Back

A solid shape with two identical ends and flat sides.

Front

What is the difference between acute, obtuse, and right angles?

Back

Acute angles are less than 90 degrees, right angles are exactly 90 degrees, and obtuse angles are greater than 90 degrees.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What is a scalene triangle?

Back

A triangle with all sides of different lengths.

Front

What is an isosceles triangle?

Back

A triangle with at least two sides of equal length.
