UNIT 7 ANGLES, TRIANGLES AND PRISMS

Front

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

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles that add up to 90 degrees.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles that add up to 180 degrees.

Front

How do you calculate the volume of a triangular prism?

Back

Volume = (Base Area × Height) of the prism.

Front

What is the measurement of a right angle?

Back

A right angle measures 90 degrees.

Front

If two angles are complementary and one angle measures 20 degrees, what is the measurement of the other angle?

Back

The other angle measures 70 degrees.

Front

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

Back

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

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height.

Front

If one angle measures 127 degrees, what type of angle is it?

Back

It is an obtuse angle.

Front

What is the definition of a prism?

Back

A prism is a solid shape with two identical ends and flat sides.
