UNIT 7 ANGLES, TRIANGLES AND PRISMS

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

What are complementary angles?

Back

Complementary angles are two angles whose sum is 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.

Front

How do you find the missing angle in a triangle?

Back

To find the missing angle, subtract the sum of the known angles from 180 degrees.

Front

What is a prism?

Back

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

Front

How do you calculate the surface area of a rectangular prism?

Back

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

Front

How do you calculate the volume of a rectangular prism?

Back

Volume = l × w × h, where l = length, w = width, h = height.

Front

What is an angle?

Back

An angle is formed by two rays with a common endpoint called the vertex.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.
